They are holding up really well. I think I want another one as both of them are already full. The only thing I don't like is about the Cowen's pages. Even though I spent a little more, the weight of the coins in the pages is still wearing out the punched holes. The albums are great though. I would still recommend them to anyone.
After a few years of enjoying these binders, I've bought another one. I plan to put all my European coins in there along with my 19th century crown collection I've been acquiring. I'll post some pictures after I get the album and swap over the coins from the other album.
