I bought this set of coasters on Ebay 5-6 years ago and was thinking of selling them.

I have no idea of the age but they seem to be maybe early 60's?

4 designs with 12 of each design inside.

Would it be better to sell the entire package together or break them up and offer them as sets of 4 to people who wanted them? I would love to keep a set for myself, but not sure I wanted to break up the set.

Any thoughts?
