An old coin's value comes from three sources: precious-metal content, collector rarity, and condition — and age alone guarantees none of them. A 2,000-year-old Roman bronze can be worth $10 while a 1943 copper penny is worth six figures. Start with the metal, the date, the mint mark, and the condition.
Silver coins (pre-1965 US dimes/quarters/halves, many European coins pre-1968) are worth at least their melt value regardless of collectibility. Gold coins even more so.
Within any series, a few date/mint combinations are scarce. The tiny letter under the date (mint mark) can turn a $2 coin into a $200 one.
Uncirculated coins are worth multiples of worn ones. Never clean a coin — cleaning destroys collector value permanently.
Double dies, off-center strikes, wrong planchets — mint errors are heavily collected and often worth far more than the regular coin.
Broad secondhand-market ranges to orient you — the exact value of your item depends on the precise model, edition and condition. Scan it for the real number.
Point your camera at the item. FlipTip identifies the exact model, edition and era, checks real listings on your country's marketplaces, and gives you a price range, a sell-speed score and a worth-it-or-skip verdict — before you buy or sell.
Check the date and country: US dimes, quarters and halves before 1965 are 90% silver; many European coins were silver into the 1960s. Silver has a distinct ring when tapped and no copper edge stripe.
No — never. Cleaning leaves microscopic scratches that collectors and grading services spot instantly, and it can cut the value by 50–90%. Sell coins exactly as found.
Rarity from errors or low mintage: the 1943 copper cent, 1955 double die, and 1909-S VDB are famous examples. Check dates, mint marks and doubling with a magnifier — or scan both sides and let FlipTip identify the variety.
Coins under ~$50 sell fine on eBay or local marketplaces. For rarities, get a second opinion from a dealer or grading service first — misidentifying one expensive coin costs more than all the cheap ones combined.
