No problem, check the date for some slight doubling on the left of the 9 and 2 in the date, plus another die break on the second S in States. VAMworld - 1921-D VAM-2B
Oh yes.. The reverse has heavy die break connecting T to the D in United and another connecting the S and T in states
nice vam/ 21s are hard to id some times so many drefarent varites listed large die brakes like yours are nice i think.
