I saw this slot for sale in the Antique store today. The write up said was unique - that only a few were made and that may be the last one. I have never seen one that took three denominations of coins before - you get a different number of pulls for each type of coin: 1 pull for 5¢, 2 pulls for 10¢, and 5 pulls for 25¢. So basically it is a Five Cent machine but you can use all the change in your pocket. Might have been a good machine for a supermarket lobby - you could get everyone's change on the way out.
