Most people think coin value is random, but it isn’t. Once you understand how type, date, condition, rarity, and demand work together, you’ll see exactly why some coins are worth a fortune and others are just loose change.
That “IBERTY” penny in your hand isn’t a jackpot. Most missing letters come from grease in the die or plain damage. Fun to keep, cool to learn from, but not the kind of error that cashes out big.
That penny with letters smeared into the rim isn’t a rare doubled die. It’s metal flow. The press shoved soft copper sideways, warping the design. Cool to study, fun to save, but not a jackpot.
Think you found a repunched mintmark? Think again. If the doubling is only on the mintmark, it’s probably just a mechanical hiccup and not a rare variety. Here’s how to tell the difference between real value and junk that only looks good under a microscope.
Think your 1965 quarter might be silver? Most aren’t, but a few rare ones are worth thousands. This guide shows you how to check the edge, weigh the coin, and know what to look for.
Before you post your coin to Reddit, stop and ask yourself if it’s something you could figure out with a quick search. Most ignored posts have the same problem. They show no clear photos, give no details, and ask no real question. This guide shows you how to do better so you actually get answers, not downvotes.
Ever found a coin with missing letters or soft details that didn’t quite look worn? You might have a grease-filled die error. These are common and usually not worth much, but they’re a great way to learn how coins are made and what to watch for when something seems off.
