Yes, that is Correct. There should be a 1980.

The clipped edge of 80 proves it is a used and inverted 2008 insert with 20 cut off. There is no 19 because it wasn’t stamped with 1980.

Simple question. Do you think this is a forgery or not?

Thanks for answering the question. My apologies for my insistence. There are some claiming that the stamp didn't have to be four numbers.

Do you think this is a forgery or not?
I believe there is very strong evidence of it being a forgery. Namely because of the missing 4 number year stamp.

So let me ask you this, you being an engineer and all...
If one were to "roll" a flat stamp, as you suggested earlier, then isn't it logical that the outside edges of the stamp would be what was worn away instead of what was in the middle and which would have an even pressure exerted upon it?
