Modern coins basically don't wear out ( maybe Zincolns corrode away). I've never seen a really worn out Jefferson nickel) copper-clad coins are Tough, they wear a lot better than silver. I'm estimating that they coined at least 5 billion Zinc cents annually since 1982, call it 150 BILLION coins....where are they ? Their can't be that many in coin collections. I can see the copper and wheats being under 1% of circulating pennies Nickels don't wear out ( at least not easily) so I think basically every one made in the last 50 years should be still circulating....if it isn't Unc it ain't worth more than melt How many nickels made since 1962....I'll guess 50 BILLION. Billions and Billions of dimes and quarters All clad coins should still be here, I've never seen one that looked like an AG Barber dime. Do these coins ever get retired by the mint as too worn ? I can't see that accounting for much of the apparent loss of coins. Nothing above is really melt material yet. Does everybody have like multiple 5 gallon jugs full of coins ? Do these coins just get lost ? I can't understand what happens to these billions of coins that should easily last 50 years in circulation, unless they become meltable for profit in theory ( copper cents) or a major design change causes hoarding ( lincoln memorial vs. Wheats). I want to know where all these coins went to ! I know pennies get thrown away like trash. I trash 5 cent deposit cans/ bottles....way too much hassle.
