If you are in Houston you could try Houston Numismatic Exchange in Rice Village. I don't really know anything about the place other than it exists, but it seems like they could give you some info.
Great idea, CaseyH! Fascinating site. They actually won't do anything Spanish before 1800 and they don't handle "cobs." By the way, for those interested, this is from CaseyH's site. Pretty interesting! "The coinage of Spain, once restricted almost exclusively to domestic circulation, ultimately became an international currency. This did not happen immediately, however, as the metal recovered from mines in America was usually shipped to the mother country in the form of ingots or crude, temporary coins called macuquinas. Known in English as “cobs,” these coins were made by simply refining the ore to slightly over 90% fineness, rolling it like cookie dough into a rod shape, and then slicing off pieces to form crude flans. These were trimmed with scissors to the prescribed weight and coined by the ancient hammer method. One die was mounted on an anvil, the flan was placed atop it, and the other die was suspended above the flan with tongs. A heavy blow or two from a sledge hammer impressed the design into both sides of the flan to form the coin. Given their crude method of manufacture, it’s not surprising that cobs are usually found irregularly shaped and with only partially visible designs. Dating and attributing these coins takes an experienced numismatist, and their collecting is usually limited to those having a deep interest in history. Cobs, like the ingots that accompanied them from America to Spain, were simply a means of accounting for the silver and gold extracted from the colonial mines. This was critical, as the king was entitled by law to twenty percent of the treasure—the “royal fifth,” which was paid to him as tribute. Since cobs were of a temporary nature and quite awkward to handle, they were not generally used as a circulating currency. Most were melted upon arrival in Europe and recoined into more conventional issues. Those which have survived intact were almost certainly recovered from the wrecks of ships bound for Spain. The minting of cobs ended by the middle of the 18th Century."
Um... yes? Admit it, you guys want my cob. bigtexxx, what does HTH mean. "Haters Tonna Hate?" "Hangs Tubercular Head?"
According to the collectible coin dealer that I know, if you go here and find a dealer near you, they should be able to help you. If they don't deal in that kind of coin, they can point you to someone that does.
i reiterate again not to sell it, however if you really must then you can call Leon in San Diego for the best advice: 858 459 2228
Thanks, weslinder: there are about 20 within 30 miles of me, so I am set. Appreciate this very much. pippendagimp, I think I'll just get it properly appraised. But when you don't have kids to leave something like this to... you know? ... and if things really do go to crap, historic value won't mean anything and it will be worth a lot less. It's kind of a "luxury" pursuit, this historic coin stuff.
if you want to cash in on the numismatic value now, then just trade the coin in for some newly minted ones instead :grin: in any case, get more than one opinion/appraisal
Here's a summary of some coin tales with Rick of Pawn Stars: http://quazen.com/recreation/collecting/real-treasures-found-in-a-las-vegas-pawnshop-part-1/
Send it to me and I'll take it this little shop I drive by everyday that has a sign that says "We buy Gold and Silver Coins". I can get it appraised for you there.
Señor B-Bob, it's "Colombia." I thought you might want to correct that bit of info, just to be respectful.
I'm surprised that some of these people don't go the extra mile and try and find out if they can sell it to the people that the Pawn Shop owner is trying to sell it to.
more specifically they don't have the time, money, connections, or know how to pull sometime like that off.
