Yes. A 10K stamp means 10 of 24 parts are pure gold (41.7%), alloyed with other metals for strength and cost. It's real gold with real melt value — just the lowest karat legally marketed as gold in the US.
It has genuine, calculable melt value like any other karat — it's simply lower per gram than 14K or 18K because it contains less pure gold. Whether it's worth selling depends on your goal: it's a legitimate, if modest, source of scrap value.
Purity is the entire difference — 10K is 41.7% gold, versus 58.3% for 14K and 75% for 18K. Weight-for-weight, higher karats always contain more gold and are worth proportionally more.
