In the graphic above, CoinQuest's
catalog value is represented by the blue horizontal line, and the purple $0 line represents no value at all. The green and orange bars represent the range of values collectors and dealers are willing to pay relative to the catalog value. When a collector buys a coin from a dealer or at auction, he or she usually pays a little below catalog value, as represented by the
average coins annotation on the green bar. If a particular coin is especially appealing, a collector may be willing to pay *over* catalog price to add it to his or her collection. This is shown by the green bar extending above the blue
catalog value line. On the dealer side, an average coin usually fetches one-half of catalog value. Only if a coin is very easy to sell will a dealer pay more.

Wear. Catalog values vary with the amount of wear on a coin. Professional numismatists and avid coin collectors use a detailed numeric
grading scale that describes wear. Coin grading is one of the joys, and one of the headaches, of coin collecting. We do not use detailed grading at CoinQuest, but only describe wear with simple adjectives shown above. If you become a collector (we hope you do!), be sure to learn all you can about accurate coin grading. It will make or break your collecting experience.

Eye Appeal. Catalog values account for wear on a coin, but not for eye appeal or damage. Wear comes from circulation and is part of a normal coin's life. Eye appeal ranges from repulsive to attractive, as shown above.

Damage. Problems inflicted on a coin over and above wear are considered damage by coin collectors, and they render the coin's value almost to zero. Problems include scratches and stains, spots and discoloration, corrosion, mounting as jewelry, gouges, nicks, and similar phyiscal damage.

Cleaning. One of the biggest problems with rare coins is cleaning. Well-meaning people often clean their coins with steel wool, silver polish, acid, or other similar desctructive processes. IF YOU ARE TEMPTED TO CLEAN YOUR COIN, DON'T DO IT. CLEANING RUINS VALUE. You can't fix eye appeal or damage by cleaning your coin.

Toning. Reactions are mixed for toned coins. Some collectors seek them out, others shun them. Toned coins have picked up impurities in the air and, over time, have become discolored. Most of the time the added color detracts from the coin's eye appeal. But sometimes toning can be quite attractive. Some adjectives used to describe toning are shown in our figure above.
