A nice centrally deficient piece.
Variety with PRV/PRVSS legend ends.
Very rare 1529 Torun penny with punched obverse legend.
There is an RV under the O*, as most likely the punching wanted to strike PRVSS instead of PO*.
Consulting this coin with Grzegorz Romanczyk, we obtained the catalog number and rarity of this numismatic coin, which is in the Catalogue of Torun, Danzig and Elblag Pennies, which is currently under editorial editing and composition and will be released on the numismatic market in a few months.
Such a variant can be found in Romanczyk's upcoming book under the number GT1529_28 with the assigned rarity RRR (4 to 10 known pieces).
Obverse: in the pearl rim the eagle of Royal Prussia, in the outer rim the legend started with a five-petal rosette:
GROSS*COMV*TERR*PRVSS*1529;
Reverse: in the pearl rim a royal bust wearing a crown and plate armor, to the right, in the outer rim a legend:
*SIGIS*AND*REX*AFTER*TO*TOCI*PRV;
