Websites dedicated to coin collecting and coin enthusiasts, such as Coin Values, provide current value information for 1943 steel pennies. Coin Value's chart includes all known variants and conditions, so that each penny can be individually evaluated and valued.
The Professional Coin Grading Service is another source for coin prices based on their face values and years issued. The website has a photograde service that allows collectors to look at coin photos and evaluate which conditions most closely resemble their coins. Other services available from the website include professional grading by mail or through an authorized dealer in order to confirm coin values.
