I own this coin:
Billon, 1.46g, 21 mm
10 Para 1223/29
But our numista says
#596 https://en.numista.com/catalogue/pieces20108.html = 1.75, 21mm, but not my date
#595 https://en.numista.com/catalogue/pieces41366.html = 0.75g, 17mm, my date, but not size or weight
What's the correct cat-number?
KrauseMishler says #596 and shows my date, but these are not the same dates than I can find in numista! Numista don't know #596 and 1223!
