I know I'm a newbie but if you're interested for years (since 1986 to be exact) I've been using an Eagle US Dollar Commen Coin album with the pages which hold 20 2 x 2 slots to store my Proof ASE's. This must be similar to TheNickelGuy's setup.
This allows me to see 20 Proof ASE's at one glance (obviously) and I don't ever take them out of their Mint supplied plastic holders.
Since there are six pages in the album, I store other Mint encapsulated coins, and some SBA's in after market capsules, etc in the same album. The edge of the binder has a place for a identifying card, so I can label it however I want.
Still can't get over your Lucite holder for Franklin halves, guess now I'll have to learn how to tap and countersink in Lucite.
