I love pressing pennies. I have about 200 from Disney World now. There are just so many to collect. They are my souvenir for the trips we take. I will usually buy the coin holder "book" there from a store. I even have a checklist of all the coin machines so I can track which ones I already have.
Make sure that you update your lists. Last Nov. hubby was done with HS and MK, only to come home and find that they changed out some dies in both locations after our trip. We found that Presscoins.com has the most accurate and up-to-date lists.
They do move machines and/or dies around and also add or take away machines.
There are a bunch of pressed pennies that are part of a series. It is fun to get all the the series.
We have all the coins at the parks, DTD, and resorts except for Shades of Green and those that were changed after Nov.
Hubby bought three ring binder scrapbooks, the fold and staple coin holders (can be found on the internet) for elongated coins, and the 20 pocket plastic pages that you can can put in the binders which hold the fold and staple holders. With over 500 pressed pennies at DW plus the ones retired, the coin holder books that you get at Disney aren't very practical.
He has actually gotten into pressed pennies, that he collects them wherever we go (zoos, museums, etc). I don't mind as he can't complain - as he presses his pennies, I get to shop.
