Watch List notes:

Mexico City, Mexico, cob 8 reales, 1715(J), full date, ex-Bob Johnson (Real Eight). S-M22; KM-47; CT-744. 27.04 grams. Choice full date (one of the best we've seen) and mintmark, some shield and most of cross despite extensive flatness (in which can be seen lots of original file marks, akin to "adjustment marks" on machine-made coins), no corrosion, with encrustation on reverse, curiously shaped as is typical for a "cabo de barra" flan (an end-piece that was cut on only one side). Pedigreed to original Real Eight member Bob Johnson, with certificate signed by him. Recovered from: Spanish 1715 Fleet, east coast of Florida

Estimate: $2500 - 5000
