Can You Spend Old Coins If They're Still Legal Tender?

By GovMint :

Generally, old coins, still considered legal tender, can be spent just like any other currency. In the U.S. for example, coins and banknotes issued by the U.S. Mint and the Bureau of Engraving and Printing retain their face value regardless of age. While some older coins may hold additional appeal to collectors due to their rarity or condition, they technically can still be used for their original intended purpose of transactions. It's always a good idea to check with financial institutions or coin dealers if you're unsure about the potential collectibility of older coins before spending them.
