I have a slabbed gold dollar that was treated by the mint with an experimental anti-tarnishing agent. It's described as a minting error. Mine is graded as MS 66. I can't seem to find much info on this. Does anyone here know anything about this coin?
This should help. Look through the entire page to find the info you might be looking for! http://www.smalldollars.com/dollar/page28.html
If I recall correctly, PCGS "used" to grade these coins but have since dropped them. More than likely due to controversy since a mildly circulated Golden Dollar looks an awful lot like it has an experimental rinse. But I'm not sure. I just know that the bottom fell out of the market once PCGS Dropped them. Or was it PCGS dropping it as a variety? I forget.
Yeah, that's it, they started grading them as errors which disqualified them from the Set Registry. Notice that the above coin does not have the "E" in front of the coin number (15000)? E is for Error.
The above MS65 cost me $99 in 2011. Heritage just recently sold an MS67 example for $40 which included the buyers premium. http://coins.ha.com/itm/errors/2001...i-tarnishing-agent-ms67-pcgs/a/131435-21854.s In January 2008, an MS64 sold for $207 which included the buyers premium. http://coins.ha.com/itm/errors/2001...-anti-tarnishing-agent-ms64-pcgs/a/454-2620.s So to answer your question..........probably not since its a fairly thin market.
That is, pardon me, stupid on the part of PCGS. An error, by definition, must be done unintentionally. This is apparently a deliberate act by the mint, otherwise how did it get there? In the same way, a RPD, RPM A DDO or a DDR are technically all varieties, just like the Cheerios dollars. Something was done to the die deliberately. An error is (for example) an off center strike, multiple strikes, wrong planchet, clipped planchets, etc. Bottom line: a variety, not an error. PCGS, please use a dictionary.
2000 was the first year of the Sac, and these coins began turning a puke green in circulation. True, the Mint was experimenting with a different rinse to counteract this, but I think that PCGS made a big mistake classifying this as any type of variety or error. Chris
