[QUOTE="robinjojo, post: 7718945, member: 110226"]Here's a coin that I've owned for while, since November 1990. It is a dated 8 reales cob of Potosi, 1617, that was salvaged from the Atocha. There are numerous coins from this salvage, sold with certificates from Mel Fisher. The appearance of these coins is one of being very bright, almost polished. This is due to the electrolysis that was used to strip away the encrusted deposits covering these coins. While it is a very effective method, and rather quick too, it does remove some of the coin's surface. The result, more often than not, is a very bright and well corroded coin. This coin underwent the electrolysis process as well. However, due to the way this coin was preserved on the ocean floor, much of the original detail still remains, including a bold date in the third quadrant on the reverse. Over the years this cob has been stored in a mania envelope, so some "color" has occurred. Still, the bright surfaces still remain, albeit somewhat more muted. The location of the date in the third quadrant, instead of the more normal fourth quadrant, suggests that this coin is one of the earlier dated emissions from this mint. 27.2 grams [ATTACH=full]1323565[/ATTACH] As a coin from the Potosi mint, the quality is definitely better than average, in terms of centering and detail. Coin production during this part of Philip III's reign was low in terms of quality control; speed of coin production seemed to be the priority. These coins, produced in primitive and often brutal conditions, are characterized with poorly prepared flans, off-center and double strikes (as can be seen on the coin's reverse), blundered legends and uneven strikes (often caused by the irregular flan surfaces). This coin was sold with an reference collection number, RC 208. However, there was no certificate, which is fine by me; I always buy based on the coin, not the certificate or slab. Please post any coins you wish. Thanks[/QUOTE]
