This particular Whitman coin folder is a larger size than the standard blue Whitman coin folders. Labeled a deluxe edition, it has hopefully enough slots to collect US Presidential dollars through 2016. Instead of being the traditional 3 fold out pages, the book has 80 slots split evenly between four pages. The first two pages are for holding your Philadelphia mint coins, and the last two are for your Denver mint coins.
Sadly this is no extra slot for holding the reverse, but fortunately (or perhaps unfortunately) the mint marks for these coins is on the edge (making the marks hard to find, and almost impossible to display in any coin collecting folder or holder.
Whitman does have a two volume set of the smaller (standard) sized books (Presidential Folder Vol. I (Official Whitman Coin Folder)), but I like the larger format of this book because I'll be able to keep the entire collection together. The size of this book is identical to Whitman's complete Fifty State Commemorative Quarter Folder: Deluxe Edition 1999-2008. In other words, this book will not be an orphan.
A tip for those of you having a hard time finding these coins: US Post Office vending machines often return change in the form of the Presidential, Sacagawea, and Anthony dollars. The majority of the coins I've got are actually the Presidential dollars and of pretty good circulated quality.
A quick note on the size of these coins ... they are actually slightly larger than US quarters. Despite what one reviewer said, this coins will not fit in a generic quarter book. My dollars fit easily into each slot.
Like most Whitman books, the two different fold out flaps of paper contain interesting information on the physical parameters of the coins, their history, and summary statistics on all the US Presidents through George W. Bush. (Carter, Bush, Clinton, and Bush are not yet eligible for being turned into coins. But Whitman included stats about their Presidencies.)
