Yes, IMO It looks like a 20 to me. Nice photos. I wasn't sure until your photos expanded, then I noticed no curvature that might suggest a 9 or an 8. Bruce
I assume you are talking about only the last digit. It can only be a 0. The only other numbers with a round top are 2, 3, 8, and 9. Since you can see more than 1/2 way down on the left side without an indent, the only possible number is the 0. Really - I measured it.
