Watch List notes:

Great Britain, uniface tin alloy Admiral Vernon medal (button), (ca. 1739), Vernon alone, extremely rare, ex-Adams. AC-UNI8. 7.59 grams; 34 mm. Weak VG with edge-piece missing and interior hole, very leaden in appearance with orange sediment as "metal detected by Jason Koos," according to Adams' tag, and probably discovered after publication because AC says: "The only specimen seen, which is badly disfigured, is in the British Museum." XRF: 60.76% tin, 36.90% lead, 2.00% antimony. Pedigreed to the John Adams Collection (with his handwritten tag).

Estimate: $500 - $1000
