Today I bought two packages of disposable razors costing a total of $4.35. I paid with a 5-dollar bill and got back 65 cents (which included a 1958 quarter).
(Quarters minted from 1964 and earlier are made of 90% silver).
Therefore at today's silver price (of $24.59 per ounce), that makes this 1958 quarter worth $4.45 in bullion value - which I could take to a coin shop and sell tomorrow.
