Just found a large amount of INDONESIAN 50 RUPIAH coins in my dryers.
They seem to be a perfect substitute for Quarters :(
Its my first time, so now i'll be keeping an eye out for this SmartyPants.
She/he used up quite a bit of dryer time & space.
NOt that a lot of you have an indonesian customer/community - in fact there are almost none even here. But still, thought i'd put the word out.
Oh, where do I start ?
France, 20 centimes, or 1 franc (BOTH the size of a quarter)
Phillipines, big influx lately
Caribbean countries
Almost every country has the same size.
Lebanon has aluminum coins,
Unfortunatly I use slides, because Keltner doesn't make acceptors for Canadian coins.
Oh, I also get American quarters, luckily, they are worth more, they may even finance my trip to Orlando in june for "cleanshow 2005"

THATS got to be a novelty: someone paying you "more" by paying American quarters ! ...sounds like a good problem.
On a technical note: I thought the job of that 'horseshoe'-shaped reader in most coin-acceptors was to measure dimensions (as well as count).
Is it that it is not very close-tolerance ?
*and they've struck again - they must have come well-stocked from home.
I feel the same as you Mike, only the opposite.
Being just Southeast of the Canadian border by a few hours I collect quite a few of your coins.
I figure by time my 20 years lease is up I should have enough for a trip to Canada.

Mike? You are leaving the country again? I did not know you were such a traveler. We are thinking of going.
Not to many coins slip by my acceptors now, I still have some twist meters on older dryers.
Pesos, Franc, some Hunduran coin, Dominca, etc, I have a big collection.
KJD,
Glad to hear your coming to Canada,
bring your hockey stick.........
Oh, wait, Americans don't play hockey .........!
Heh heh heh ;-)
At one time I got a lot of Chinese coin in soap vending machine, I raised price from 50 cent to 75 cent then this guy/gal goes somewhere to spend his/her Chinese coin.

I just got another coin that goes through all my 25 cent slots.
It says TEN PENCE on one side
and has Queen Elizabeth II on the other side just like a canadian coin.
Can anyone tell me where it is from and how much is TEN PENCE?

It's from England, worth one tenth of a pound, ( I think about 15 cents U.S. but don't quote me);)
As an aside, England didn't think it was necessary to put the country name on their coins or stamps for that matter.
They are the only country to do so, I believe (I know it's true for stamps, as they "invented" the stamp)

OK, most coins are round. And there are only so many sizes they can be made to. WIth so many currencies in the world is inevitable that some of them will be the same size. And they rarely have equal value. Mexicans have trouble with the US Nickle fitting in mechanisms that accept the One Peso. THen there are the examples cite above. THere isn't a whole lot to be done about it. Most mechanisms are simple devices, measuring the diameter and thickness. Some drops have magnets to keep out coins with ferrous content (Canadian quarters are an example) But most push/pull style do not have magnets and even those that do only stop magnetic based coins, others will just fly on through. As long as we are dealing with very simple mechanical devices, we are stuck with the situation.

In our payphones, we have a mix of mechanical and electronic coin mechanisms. The electronic ones are expensive, but are very good at rejecting almost everything that is not US coinage.
The mechanical ones (made by Coinco) sort three denominations by diameter, and then they weigh them. They also reject ferrous coins. If it's the size of a quarter, it should weigh about what a quarter weighs, and it should not attract a magnet. They can reject those aluminum Chinese coins that my laundry machines accept. The mechanism is a lot larger than the one in the laundry machines, and has a lot more moving parts. Yet there is lots more room in a laundry machine than in a telephone.
Somehow, I would expect that a coin acceptor that only accepts one denomination would be better at rejecting fakes. But my slides on the old Maytag tops, and my Greenwald dryer timers seem to accept nearly everything.

Ok, lets explain how the push pull style mechanisms work. If you take a coin and hold it at its diameter between your fingers, you can tell a nickle from the quarter by you 'kinesthetic" sense. You feel the difference in diameter. Now reach up and take the coin, and then slide it back so you finger spread apart. This is essential how a slide works.
It is much more senstivie than your fingers. Proper set up, and properly maintained and cleaned, it will detect the difference beteen coins of of about .008 inches. (three sheets of paper) When the coins are inserted into the slide, the slide must be pushed in about an inch to even get them into the machine. Then the measuring takes place, (remember pushing the coin between your fingers?) that takes up another 1" Then, once the finger says this is the right diameter, you must push it another 1-1 1/4" to let the coins fall, and to push the timer to intitate the cycle. What you have is basically a "snap" guage. as used in manufacturing to quickly check diameter of parts off of lathes and such. All of this is linear motion and the only times gravity kicks in is when the coins are released to fall into the vault.
These devices, in one form or another have been around since the 1920's. At that time drop mechanisms, even on payphones were unreliable and they were strictly electrical in nature. that is the coin would trip a switch. With push pull mechs it is all mechanical, hence their early use on simple mechanical free standing vending machines. They are still used on these today, look at baseball card machines, & pool tables.
Why the push pulls were chosen when coin laundry came about I am not sure. But they have been there since 1946 after the war. The flat laydowns changed to verticals, but the principle remains the same. There ARE mechanisms that might work better today. Keltner makes one that is very very senstive, It only accepts quarters and nothing else. It also cost 5 times what a push pull mech costs.
WE do not produce drop mechanisms, but I am familiar with the ones used in Laundry. In fact, at one point we considered buying AirPax when it was offered to us. We are just as glad today that they declined our offer. It was unchanged since the 60's. Hundreds of thousands were produced, but they were not accurate, they were not adjustable. They were not substantial in their construction.
Of those made today, in my judgment, the best is the imported one by Hanke. These are senstive but still rugged mechanisms. there is provision for some adjustments. they have the magnet built in. But even they have issues. First it's cost. About $90 as a replacement for an OEM mech. They are only available as replacement OEM Parts. (Believe me, we have tried to get the line as an aftermarket item) THen with drop mechs you have the further issue of fitting the machine. Those that use Hanke today almost all use the same size face plate. but over the decades there have been a different face plate for all the different makes of machines. WIth push/pull it doesn't matter if you have ESD, GREENWALD, Monarch, or even old ABT chutes, they all interchange ( exception, V-8's will not fit Old Maytage V-5's) But with the drops you are usually confined to replacing a mechanism with the same mechanism.
The mechanism that can sort coins, and use the cradle as a part of the evaluation (there is also a "bounce" test in many. the coin hits a metal surface as it falls and must bounce into the cradel for further measurement, or if is the wrong material and does not bounce right it fails), But these mechansims are over 4" tall not counting the area into which the coin is entered, and the area where it falls over the switch. Keep in mind that even on laundry machines using drop mechs today, there is insufficient room for that tall a mechanism. Most of these machine are adapated from OPL designs and the coin apparatus and coin box are tucked into available space as an afterthought.
It all comes back to money. ESD, or Greenwald or Monarch, can come up with the greatest GeeGolly Whizbang ever. But it has to go on the laundry equipment. If it requires any modification to the equipment the manufacturers will say "let somebody else try it first". They can't afford to make changes to the machine, adding expense to its final cost, while the laundries buy the cheapest rather than the best for the money. Several companies have already found that out, much to their financial ruin.
Who can change all of this? Not one of you. But if ALL laundries insisited they were willing to pay for better designs both for coin acceptance and for secure coin coin boxes, it might have worked. But now it is too late. The companies will tell you that they HAVE come up with a better solution, Cards!

I would have to say that Keltner is the best drop. I have replaced many of the OEM Hanke drops on my machines with Keltners. These units eliminate almost all coin jams, a jam is very very rare.

I measured the height of my MicroCoin QL on my coin op internet kiosk & it is a little over 4 inches on the inner functioning part. This coin drop has been flawless for over 5 years from my experience.
I have all Ketner on washers. Many many times, when people just close the door, the machine will start free. Sometimes I can experience this myself. The problem is it does not repeat all the time, just sometimes. I just could not find out what's wrong with it besides sending it in for another one.
