Pictured is a 1787 Republic of Vermont Britannia copper that I also obtained in the last week. Based on diagnostics, I'm rather confident that this specimen is a RR-13 / Bressett 17-V / W-2255. Particulars of this specimen include: Machin's Mills issue; The majority of the reverses for this issue have very worn lettering, presumably because the dies used were intentionally ground down to give a worn appearance, or were used first to mass produce counterfeit English halfpence and then used for minting Vermonts; Rarity: URS-12 - 1250 known specimens exist. I spotted the same variety in very similar condition (Choice Fine) online last night for around $450... I paid half of that! Any comments and thoughts about it are appreciated and welcomed!
