@jim a baranak …please do the following next time you post: 1. Tell us what sort of doubling you suspect. Don’t make us guess. 2. Post a close-up of the doubling you are seeing. 3. Confirm the doubling variety at Variety Vista or Wexler. After 42 years just about all of the 1981 doubling varieties have been identified and covered by these 2 sites. Doing the above will let members offer you better help…imo…Spark
I see what I think you are referring to, the line on the letters in the word STATES, but I don't see it elsewhere, so I'm going with worn die on this one.
