I looked up a wheat penny chart and it said, a 1943 penny is worth about 15 cents, a 1943 penny with a d mint-mark is worth about 18 cents, and a 1943 penny with an s mint-mark is worth about 20 cents. I'm not sure how recent the chart is, because if the chart is old they could be worth a bit more. But I'm not sure
