Got this one a few weeks ago for a little under $12. It was sold as: "Brandenburg, 1624, 1/24 thaler" With Central Europe in the 1600s, I find the attributions are as likely to be wrong as not. I'm not 100% sure I have an exact match, but I think it is this, variant Górecki K.14.2.b. Obverse: SIGIS 3 DG 3 REX PMDL (Sigismund III, by the Grace of God, 3 [polker], King of Poland and Grand Duke of Lithuania) Reverse: MONE NO. W REX POL. Z4 I think the bottom W is Krakow mintmaster Stanislaw Warszycki (1614-16) The "14" around the orb is the date [16]24 and the Z4 indicates that it is 1/24 of some larger monetary unit (a thaler?) 1.11 g silver, ~20 mm diameter I know my local coin shop will take it back for exchange if I want, but I'm not sure if $12 is a reasonable price for this coin anyway. I'm useless at estimating grades on older coins like this. If I have the right variant, Krause (2011) has it at $7 in G and $22.50 in VG. The reverse seems more like a weak strike than heavy wear to me. Would you keep it or trade it back for something else? All advice welcomed, thanks.
