Good video man, My only problem with investing in copper and nickel is that there is a melt ban on them currently. It's illegal to melt these coins down, as of now. So the people who are collecting these coins will amass huge stockpiles, and when they lift the melt ban (if ever) then you will have a massive influx of people taking their hoards in to get the metal value, and with that influx of metal coming back into the market, wouldn't that drive the price down? I'm not economist but that's just what I see happening.
I'm not going to lie, I do hoard copper cents, not nickels yet, but I work at a gas station where I can sort through coins and buy the ones that I want out of the drawer. I'm sure if they lifted the melt ban it would take a few days/weeks for the price to drop, but still increase in supply would probably drive the price down quite a bit.
