Nothing good from my recent purchases since we already did "oldest bimetallic coin" recently.
Lets see how this goes.
Finland 1917 50 penniä, KM# 2.2, mintage 3,972,000
Finland 1917 50 penniä, KM# 20, mintage 570,000
Post two coins from the same country and denomination and compare the mintages. Take the coin with the higher mintage and devide by the lower mintage. This will be your base score.
Same year, different types, same denomination - 2x base score Different year, same type - 1x Different year, different type, but same denomination - 0.5x Any two coins from the same country - participation
A type will have a unique catalog number. I would prefer that you use KM or N numbers if possible. Edit: I forgot to add that they must be coins for circulation.
Please use reputable sources for your mintage numbers.
For the coins above, the score would be 2*3972k/570k=13.9
Highest score wins. Please round final score to the nearest tenth.
I'm interested to see what kind of spread we have for this round. According to my collection spreadsheet, my highest scoring pair is Finland 1918 5 penniä KM# 21 and KM# 22 for 244 points. Unfortunately I couldn't locate KM# 22 for pictures to use here
