Is there a difference between the 32 cent g rate stamp and the make up g stamp?
Yes there is.
The 'G' Stamp was a 32 cent stamp and was issued because of the
rate change from 29 cents to 32 cents in 1994.
The make up 'G' stamp (3 cents) was for people who had left over
29 cent stamps to use both stamps on a envelope, 29 cent plus 3
cent (make up 'G' stamp) to equal the new rate of 32 cents.
