Idk how it happened. 2020 was my year for reviving my coin collection. I’ve always just loved the finish of proofs!
I have a bigger problem than you do. I have them back to 1942, excluding the sets with missing mint marks. I have a 1936 Proof set and have thought about getting the rest of the coins in between. The trouble is I love the Walkers and Mercuries, but get bored with the Lincoln cents, Jefferson Nickels and Washington quarters.
I don't think buying them is a problem, storing them however, might be. it also looks like you are slacking in the silver proof set department. LOL
Loved reading all of your responses! Thanks everyone. I suppose once I finished I can start with the silver sets, then go back before '55 all the way to '36 eventually. My girlfriend is a bit concerned we don't have the space. So far for me though, not a single bit of buyers remorse hah!
