R7+ 1786 New Jersey Colonial Copper Coin (Maris 24-Q)
This NJ copper (I am told) is possibly an early 20th century cast copy or electrotype copy of the R7+ 1786 New Jersey Colonial Copper Coin Maris 24-Q Plate coin. Maybe a contemporary counterfeit. The original coin weighs about 135-150 grains while this one is 247 grains (the heaviest NJ copper listed in Breen is 203 grains). Diameter is true at: 28.02mm. The die marks/cracks on the reverse shield of the original 1881 Maris Plate 24-Q coin seem to match with several of the marks/digs on the "copy" coin (see side by side comparison).
Only 5 examples are known of the 24-Q (the 5th discovered about a year ago), with the last two sold at the Mar 2017 Baltimore auction by Sacks Bowers Whitman Coins and Collectibles Expo (lot# 259) and another at the Nov 2015 Stacks Bowers auction in Baltimore (lot# 5398)
What are your thoughts? Worth sending it to NGC? Thank you.
