I have a bicentennial quarter on the reverse side it looks like the e in e pluribus is double die and the d mint mark on the obverse is a blob how much is it worth?
I see a little damage to the direct left of the E (in E PLURIBUS), and a simple/common filled mintmark. Sorry, Bobby...
The correct terminology is Doubled Die, not Double I want to share this webpage with you - http://www.error-ref.com/double-die/ The D Mintmark is Circulation wear, a hit or a tiny Die Chip. Worth.. 25 Cents
