1. What years did the US melt down a ton of silver dollars? I remember reading about them doing that. 2. Were a lot of silver coins hoarded after 1964? 3. When did the US announce they were changing away from silver coins to clad? 4. Was it common to find silver coins in change after 1964. 5. Did a lot of silver coins disappear from circulation after the hunt's brother silver hoarding in 79/80?
I don't know. Yes. 1963, I believe. Yes, common until at least the 70s. Yes, but not a "lot" as much of it was already gone.
Around 270 million silver dollars were melted due to the Pittman act of 1918 There were around 570 million of Morgan dollars minted in total before 1918, so they melted nearly half of them.
Did they tabulate which ones they melted? If they melted a whole bunch of one year that could actually make one year worth more if you don't go by mintage numbers.
Nobody knows exactly what years/MMs were melted. It is often assumed that many common date silver coins were melted. If you search online, you can find estimates for denominations you are interested in, but these are only estimates. TC
1.Pitman act of 1918. No they didn't record dates and mints. 2. Yes 3. It was known to be in the workssince around 1963 the act that officially created the clad coins was the Coinage Act of 1965 passed in May of 1965. 4. Yes but they disappear rapidly and most of them were gone by 1968 or 69. 5. Silver was long gone from circulation before the HUnt Brothers ran up silver in 79.
One interesting piece of trivia on the subject. For the 1964 90% silvers dimes, quarters and halves, they actually minted the 90% type up until 1966 with the 1964 date. So you cannot tell when a '64 silver coin was actually minted. Mike
So now that you got your research done...now is time to talk about a finder's fee for these gentlemen.
You can also find it in the Red Book of Morgan Dollars as to amount melted and estimated survival population. As always, nobody knows if the 1895 Philadelphia Mint Morgans intended for circulation ever even existed.
