Recently purchased a set of 1953 coins and the seller indicated they came with the original small mint box (not a special presentation case).
The plastic sleeves contained individual coins, but they were open. The plastic feels similar to the early PL sets, but that was probably the standard plastic back then. The sleeves perfectly match the size of the box and it looks like the sleeves were all stapled together. Thoughts?
Will post pictures of coins at a later date.
