1997 Proof And a freebie thrown in with another purchase. Edit in response to next post: @Jorge Caudelaro , this does look like it was part of a Mint uncirculated set. The blue stripe along the edge of the plastic is hard to see in this picture. I matched it up to an offering on Amazon.
I decided to up-date my 1983 DDR, sellers photos. Plus I figured out how to straighten a photo using PhotoScape.
