Watch List notes:

British Coins, Victoria (1837-1901), proof bronze farthing, 1860, toothed border, 4 berries in wreath, struck en médaille, young bust left, rev. Britannia standing right, with shield and trident (P.-; F.500 [R19]), certified and graded by CGS UK as CGS 88, as struck, choice toned with a hint of lustre and excessively rare
Since Freeman listed this coin as R19 (2-5 examples known), it is unsurprising that Peck never saw one.
(800-1000 GBP)
