Watch List notes:

Copper cannonball, very rare (unique from this wreck). 7390 grams, 4-1/2" in diameter. Among a group of rare bronze cannonballs from this wreck was this single pure-copper ball, distinguished from the rest by darker, smoother surfaces (with some copper color peeking through), by size a 12- or 18-pounder, sure to be of interest to serious cannonball collectors but also important for shipwreck collectors who recognize the general scarcity of available artifacts from this wreck. With original certificate from the salvagers. Recovered from: Capitana, sunk in 1654 off Chanduy, Ecuador

Estimate: $750
