My first pickup was an aftermarket "unsold" coin from Heritage NY Sale. A previous 1782 had sold for $3055US in 2015 it was MS-62. This coin was a MS-63/ got it for opening bid of 1900 AV 2 Thaler 1782 Schwerin Mint Grand Duke Friedrich I of Mecklenburg-Schwerin Mintage 1100 3.19 g. 24mm.
from my 3rd edition 2002 Krause world coin catalog... KM#210 .875 gold, weight-3.12 g or .0878 oz. , Ruler-Frederich II, mintage-1,625 highest grade/values- UNC-$2,250.00 no values for BU grade. so I am guessing way higher. Amazing rare coin.
