I will try something different, post your webbing. Largest physical coin webbing size or largest coin denomination (that the webbing is for) wins. The type of coin that the webbing is from must be included in the picture with the webbing. See example photo below.
When I did some halves last Wednesday, I found this minor revese struck through grease. Very little design elements are visible in hand, but they are there. Other coin for comparison only.
I will keep it as a fun curiosity just because of its location.
