See, between 1932 and 1964, quarters contained 90% silver, which means each quarter contains 0.1808 troy ounces of silver. Now, the price of silver fluctuates, but Coinflation.com calculates that at $23.75 per troy ounce, the silver in these hard-to-find coins is worth around $4.29. Depending on the size of the cone and your local ice cream shops’ prices for cones, that may not be a bad deal.
However, that old coin could be worth a lot more depending on the condition and rarity. Many of these quarters go for a minimum of $5.75 to collectors, with some going significantly higher, with the rarest, uncirculated quarters going for several hundred dollars.
Even if you have a completely average silver quarter, it’s probably best to hold on to it and just go out of pocket for that ice cream cone.
