A rarer vintage of two-dollar coins, minted in the year of the work on the monetary reform change.
Although if you type in the numismatic archives with the keyword two-zloty 1771, you'll get a lot of quotations, half of them are for proof coins issued in pure silver, on the reverse of which you don't see a coat of arms shield, but a hand inspecting the coin on a proof stone. A circulated version, in very nice condition like this one, is difficult to acquire for a collection.
A variant with a ribbon over palm branches.
Variant with two leaves on the left side of the wreath.
