Thank You for the answer 🤗
On the edge is written 1969, does that change anything?
Well…it may mean that it's a different medal than the one linked (which states it has a smooth edge) or the one in the catalog has some wrong information about it. Is yours 10.1 g, 28 mm?
1993 - 1143 = 850. 1969 - 1143 = 826 which seems silly to celebrate.
