I view error coins different than most. To me an error coin is a one of a kind event that happened during the strike or before the strike. Mike Diamond identifies different events that create an error coin. (which will keep you busy for several days reading this information)
http://www.error-ref.com/To me coins struck from worn dies, cracked dies, excessive polished dies and broken dies are
not error coins. They are the result of die use and events that happen to the die during the dies life. IE cracks/chips/breaks/over polishing causing die abrasion/die fatigue/and so forth. (extreme examples do peak interest as a collectables) Shattered die examples,
Cuds, a full crack across the surface of the die and so on. Striking events that happen during the strike are a collectable. Wrong metal, double strike, flip over strikes, broadstrikes, (one time events), brockage, mirror brockage ETC. The less often something happens, the more collectable the coin.
Discolored coins, damaged coins, painted, burned, cleaned coins, ETC are events that happen after the coins was struck. (
PSD Post
Strike
Damaged) Done outside the mint do not make them collectable. Common events I mentioned before are common coins.
Variety coins are different than error coins. An error coin was an event that happend. But a variety is created by a hubbing error while creating a die/a miss punching of the die with a mint mark punch, date punch (happened mostly on 19 century coins) over mint mark punchings. The reason they are different are that each coin struck with that die will show the same variety coin after to for the life of the die. (allowances are made for die weak that can affect the variety) Dies that show die wear are often discounted if they are affect drastically because of die wear.
But you coin is showing events that happen to the coin after it was struck. (
PSD) if a coin is left outside for a time, they coin can discolor. If a coin was painted/plated (
PSD)/burned/bent/altered that is just a damaged coin. Not an error. Hope this helps.
