Just purchased a decent George VI cent for my type set. There are six George VI cent types, and now I have half of the slots filled. One more cheap one to go and the last two are bloody expensive in any nice condition.

Can you have 2 of the same set?
I have a bad addiction to Walking Liberty Halves. Besides my main collections of them, I've also started a 2nd "short set" 1941-1947 in all PCGS OGH's. I wouldn't be reusing any of the same coins in multiple sets in the same categories.
But from what I'm seeing I don't see an option to start a new set if you already have one.

I've just added a set "Howfast's Early Dollars" (Early Dollars Basic Set with Overdates, 1794-1803).
