Every hole in this album is filled. As you can see, the dates for most all of the early coins are very rough. Some have been acid dated, others look like they've been brought out some other way. The coin in the 13s type 2 slot is a type 1. Some of the mint marks are very light as well, but I did check the 14d and 21s and have included pics of many of the better dates. I won't guarantee that this is a complete set due to the roughness of the dates, but I'm happy to provide more photos of individual coins upon request.
