- [1970 S Doubled Die Penny (DDO-001) Guide](https://richofferrorcoins.com/1970-s-doubled-die-penny-ddo-001-guide/): 1970-S DDO Penny: The Rare Doubled Die Lincoln Cent Worth Thousands The 1970-S DDO Penny is one of the most valuable Lincoln cent varieties from the 1970s. At first glance, it looks like a regular 1970 penny with an “S” mint mark.

Remember to check back with us for new content. Learn all about valuable error coins and varieties here at Rich Off Error Coins. This coin is officially known by collectors as […]
- [1980 DDO Penny: How to Identify the Real Doubled Die (and What It’s Worth)](https://richofferrorcoins.com/1980-ddo-penny/): If you’re searching for a 1980 DDO penny, you’re looking for a Doubled Die Obverse Lincoln cent—most commonly the 1980 (Philadelphia / no-mint-mark) DDO FS-101. This variety shows true hub doubling (not damage, not “shelf-like” machine doubling), and it’s collected because the doubling is visible in key obverse areas when you know where to look. Explanation: What “DDO” Means on a 1980 Penny A doubled die obverse happens before coins are struck—during die creation—so the doubling is part of the design itself. That’s why strong examples show clean, separated doubling rather than a flat, smeared look. Important detail: Just a quick […]
- [Coin Errors and Varieties](https://richofferrorcoins.com/coin-errors-and-varieties/): If you’ve been searching for coin errors and varieties, you’re not alone—most collectors (and pocket-change hunters) mix the two up at first. That confusion can be expensive: it leads to paying “error coin” prices for damaged coins, missing real die varieties hiding in plain sight, or submitting the wrong thing for attribution and grading. This guide breaks it down in plain English, shows you how to tell the difference, and gives realistic value expectations—without the hype. What’s the Difference Between Coin Errors and Varieties? Here’s the core rule that saves collectors the most money: Coin Varieties (Die-Related and Repeatable) A coin […]
- [1987 D Over D Penny Value and Identification Guide (FS-501)](https://richofferrorcoins.com/1987-d-over-d-penny-value-and-identification-guide-fs-501/): The 1987 D over D penny is a recognized repunched mint mark variety, not just a random damaged cent with a funny-looking mintmark. In collector language, this coin is the 1987-D/D Lincoln cent FS-501, and Variety Vista cross-references it as 1987-D RPM-003, D/D North. PCGS also recognizes it under the FS-501 attribution. That matters because the phrase people search for is usually “1987 D over D penny,” while the attribution collectors and grading services care about is FS-501. So if you are hunting this coin in rolls, dealer junk boxes, or old copper-lot flips, you want both things in your head […]

- [Coin Errors: Comprehensive Guide to Types, Identification, and Realistic Values](https://richofferrorcoins.com/coin-errors-comprehensive-guide/): Coin Errors are mint-made mistakes—accidents that happen during blank (planchet) production, die preparation, striking, or ejection. Because they’re created at the Mint, genuine errors have repeatable diagnostics: the shape of the strike, the way metal flows, the presence (or absence) of rim/collar effects, and the “story” that matches a specific step of the minting process.
