Don't throw it away. Keep it as an educational tool for others. Or sell it to someone who would use it that way. What's the legality on that, anyway? Anyone know? I'd buy it for that reason if I knew it was legal to own.
Here's whet you should do: http://www.money.org/communications/consumer-awareness/counterfeit-qa.aspx Q: Is it illegal to own counterfeit United States coins? A: The short answer is "yes." Since most coins produced by the U.S. Mint are legal tender even if they haven't circulated for decades or longer (such as silver dollars and the various gold denominations), counterfeit specimens are illegal to knowingly own, buy, sell or trade, regardless of your intentions. While the U. S. Secret Service very rarely seizes counterfeit coins, it has been known to do so. Many hobbyists claim they can have counterfeits in their collections as long as they clearly identify them as such or use them solely for reference. In the eyes of the law, neither justification is legitimate. Whenever a hobbyist comes across a counterfeit or altered coin, I generally recommend he consider donating it to the American Numismatic Association's Edward C. Rochette Money Museum. The ANA has been granted permission to maintain a collection of counterfeit coins for educational purposes, and each year, hundreds of numismatists study it. Thanks to the ANA, these fakes are forever removed from the marketplace. You might even be able to claim it as a charitable gift!
But they were accidentally monetized again in 1965. I'm not sure where they stand now. http://en.wikipedia.org/wiki/Trade_dollar_(United_States_coin)
When did PCGS start using Counterfeit , instead of Questionable Authenticity , or whatever they used . Or is it NGC that uses that ?
It was funny... in the email of results I got from PCGS it read "questionable authenticity". But the holder itself read "counterfeit."
