Im a stone mason and a coin collector and wanted to share a lesson learned story. A few years ago we did a stone job in wildwood new jersey , and after completely the job the owners asked us if we wanted a bar top he aquired from the wharf in wildwood. He was only going to use half of it in his house and had no need for the other half. The bar top is very pretty and has all sorts of spanish and mexican coins embedded in it along with rope from an old ship and wooden planks off the boat. Well we trimmed the bartop to fit the area we had built for it in our own house and I told my dad that I was going to dig out the coins that were embedded in the bartop . One of the coins was a 1/5th of a spanish 8 reales but it was stamped s martin and I passed it off as a copy and stamped with the maker and put it aside, well my dad decided to drill a hole in it and hang it with a key that was also dug out of the bar top. Two days ago I searched for information about it and found out that one in vf 25 condition had sold on heritage auction last year for $3200! My dad was like really! I'm sure he will never drill a hole in any coin again! The coin is Dutch-French Colony. 18 Stuivers, St MARTIN with arrows counterstamped on 1/5-cut of Mo 8 Reales ND, KM12, Scholten-1416, 5.54g, Pr. page 258, fig. 3, 85.5gr, VF25 NGC. Does anyone know how rare these are or how hard to come by?
