Is old ammunition valuable?
Some is worthless, (or almost worthless) and some is very valuable, but most is only worth relatively little. Just as with some stuffed animal toys, certain people will pay hundreds of dollars for certain cartridges, while other people would not want them at any price. “Old” ammunition generally has very low values (probably less than a dollar, and often only a few pennies per cartridge). This is stuff that shooters are reluctant to use, but not yet desired by collectors. “Collectors’ cartridges” are probably 50 years or older, and have some feature that appeals to collectors. Values will generally be in the dollar or less range, but quite a few will bring higher prices with values in the $10.00-20.00 range not unusual, and some bringing much more. Grungy, corroded, dented cartridges have the very least value (if any), while bright examples in a sealed box have the highest value. The only sure way to find the value of anything is for a willing buyer and a willing seller to make a deal.
