I know the Ike's have many DD's, and not uncommon. I was trying to match a number (WDDR) but could not find a 1977 on Wexler or Variety Vista. Any ideas where I can look for match? Thank you.
Proof coins are struck 'at least twice' according to the US Mint I would be more confidence saying this doubling is due to the two strikes, rather than a doubled die.
