Watch List notes:

Large Colombian gold bar, 1626 grams, marked with fineness XXII (22K), foundry/assayer BARBAROSA and complete circular tax stamp with lions and castles in a crowned shield, plated in Craig & Richards, from the 1715 Fleet. 5-1/2" x 2" x 5/8". Somewhat rough surfaces (mostly due to pits that are probably from contaminants that were burned or corroded away) but with clear and bold markings, the circular tax stamp very reminiscent of Colombian gold cobs but clearly of Colombian origin anyway based on the foundry/assayer inside an incuse box within a border of dots, the fineness XXII all within a box too, also with modern 5 stamped into the bottom by Treasure Salvors. Curiously, there does not appear to be any sign of an assayer's "bite." Gold bars from the 1715 Fleet are rare and highly in demand. From the 1715 Fleet, plated on page 114 and back cover of Spanish Treasure Bars (Craig & Richards, 2003), with Fisher photo-certificate #1715-GB5.

Estimate: $80000 - 160000
