They were issued by the mint, but we're never released, most were melted down Sent from my iPhone using Tapatalk
If it's a Carr overstrike, it's worth some serious money. However, I think regular fake 1964-D dollars are a lot more common than the Carr issue. If it's a real mint-produced 1964-D dollar, it's worth a lot of coverage in the numismatic media, and a lot of legal trouble for the holder. As far as I know, there's no legal path to ownership of one of the originals, even if any of them escaped from the Mint. For yours, the very first step is to see whether it's attracted to a magnet. If so, it's a low-value fake. If not, the next step is to weigh it on an accurate high-resolution scale, and report back to us.
I'm not sure what the indicators are for a Carr original, but it's kind of unlikely that you'd find one separated from the packaging that identifies it.
For one thing it will have a repunched mintmark. And it you examine it closely most of them have traces of the original underlying Peace dollar that he used as a planchet.
Die chip or no, the position of the mintmark on that image of the Carr dollar is vastly different from the position on the picture you originally posted. I'm afraid you're out of luck as far as having a Carr dollar. Next steps, again, are the weight and magnetism checks.
