Yeah, I've settled into a collection that allows for a lot of impulse buying. As long as its dated '82, its open to any country, denomination, and century. I'd like to think the list of coins I will overspend on during an impulse buy is relatively short though, but it is certainly known to happen for things I know wont come around again for a while and I have few regrets in the coin box.
In analyzing the data, I still love the Bust Dimes. Braided Cents and 2 Cents seem like something fun. For 20th century, I'd personally go with the Buffaloes.
