X2an Pillar of the Community Sweden 1078 Posts	Posted 08/19/2018 08:04 am I picked this piece up today. After getting rid of the mountings I went immediately to identification. It's definitely a ½ Afghani (1350). What doesn't check out is the diameter and weight, compared to Numista's page. According to Numista, the piece should be Ø24mm, 5g. The piece pictured measures Ø21mm, 3 or 4g (household scale doesn't help too much). My question is, is there any explanation or documentation about this? No doubts in my mind about its authenticity. Edge is plain, contrary to Numista's information. Report this Post to the Staff

Spence Moderator United States 34397 Posts	Posted 08/19/2018 08:29 am @x2an, based on the proximity of the wreaths to the rim, it looks to me like the edge of this coin has been shaved, perhaps in an attempt to get a little silver "for free". That might explain the lack of milling on the edge as well as the low weight and small planchet size.

tdziemia Pillar of the Community United States 7935 Posts	Posted 08/19/2018 08:44 am Removing 3 mm from a 24 mm coin should reduce the mass by about 24%, which is consistent with the discussion thus far (so, a 5 g. coin would be reduced to 3.5 to 4 g). And, to get a fairly accurate weight without an accurate scale, you can use the technique described here : http://goccf.com/t/326203 Report this Post to the Staff

This seems almost obvious when the edge is supposed to be milled but is entirely plain. This didn't cross my mind at all, thanks! I put a coin with the intended diameter (24mm, Panama 1/4 Balboa) for comparison with Numista's issue-free image: It very well looks like the edges have been cut off. I can't see any obvious filing marks on teh edges but they have most likely been smoothed down from circulation and jewelry wear.
