Gosh I hate duplicates but am having a hard time parting with some.

I see duplicates as taking up space and money that could be spent on more coins for my main collection, but I have a hard time parting with some, esp with such a fine grading scale in place... 66+,67,67+ etc. I'm afraid everything I'll sell will be upgraded by the buyer... and it's not necc the money they might make that will bother me the most... but that it'll be a new coin graded higher than the one I kept. (ie a new top grade for the date/mm, this has actually already happened to me).

Coins are like stocks, if you sell you need to never look back.
