IMHO, the small ANACS white holders are going up in price and becoming harder and harder to find. In 2009 I decided to put a Walker complete collection together in old ANACS white holders. I knew these holders were getting crossed to PCGS and NGC and wanted a modest collection to save the ANA history at the very least. It was fun and I found that the coins were either graded accurately or one grade under for the early slabs say through to mid 90's. ANACS went to a lager version of the two ANACS triangles on the back along with 7 digit certification numbers. It was in these later white slabs that the grading was sometimes a bit slack. I started trying to buy just 6 digits serial numbers. I lack 12 coins to complete the collection. Most of the 30's and all of the 40's are MS65 while the early issues are all Fine to EF with a few AU. This has been a blast. The price has steadly gone up since 2009 and now if you look at EBay sales history you'll be surprised to find that the ANACS coins listed under a "Buy it Now" tag are commanding PCGS list prices for 1916 through the mid 30's coins.
