Hi,

 

What is the actual theoretical weight of this coin?

 

Numista page says 17mm.

SCWC says 16.59mm.

 

I also found these two diameters on different website, while I measure 17.41mm on my coin.

Mine is 1.84 g and 17.59 mm.

 

Assuming a tolerance of +/- 4% on both you'd have to get the target from either the mint, Bulgarian government or measure about 100 UNC coins.

 

But, 16.59 mm does seem too low (mine would be +6% off) while 17.0 mm could be right (mine is +3% off).

 

The coin page originally had 16.59 mm and somewhere between 2016 and 2022 it was changed to 17 mm. Maybe the person who made that change just rounded off to the nearest mm.

Mine has a diameter 17.56, a weight of 1.82 and thickness of 1.01. The grade, I estimated to AU some years ago!
