Coin Proof sets from 1999 to 2016  and uncirculated coin sets from 1999 to 2016?

Did you collect these as a Hobby, or as an investment?

[SweetieJean]

Gold, silver, gems, stamps, coins, etc., are capital assets except when they are held for sale by a dealer. Any gain or loss from their sale or exchange generally is a capital gain or loss. If you are a dealer, the amount received from the sale is ordinary business income.

So, yes, you can deduct the difference as a loss.
