Out of curiousity approximately how many penny presses are located throughout the resort?
And on a similar thought do they still have the mystery pin machines at epcot?
Penny (and quarter) presses - I am going to guess over 100.
You can ask for a print out of all the locations from any CM that has a printer. Ask at your resort lobby, Last time I asked for a print out (4 - 5 years ago at least) it was about 5 pages long, and assuming 20 locations per page, thats how I arrived at 100 locations (throughout the entire WDW)

They have lists of all the coin presses on the property in a variety of formats.
The best one I think is the PDF version - 16 pages long in a checklist format so you can track all the coins you have/need to complete your collection. There are literally hundreds of coins in each park, you could spend almost as much pressing coins as you do on the trip itself!
