Since my blog has began to focus more and more on coins I figured I'd offer up some more wisdom (ha) regarding what to look for when considering buying a coin.
Coins often become toned after years of being stored away. Vapors from drawer liners, coin roll paper, shelving paper etc. cause all sorts of toning. Coin toning can intrinsically increase or decrease the value of coins. Natural coin toning can be quite beautiful. It can also be outrageously ugly.
And because beauty is often times in the eye of the beholder, placing a value on a coin due to its toning can present problems.
A coin that’s toned is in a normal "stage" of its life. It won’t disintegrate away before your eyes. Even in worst cases, the tone color will normally take centuries to reach its very darkest and usually its least attractive appearance.
There are several factors in determining the value of a coin, but at the very top for most people is its eye appeal. If a coin is ugly, unless extremely rare, people aren’t going to buy it and the value will be lower. If a coin is attractive AND toned, it’ll likely be worth more to some people.
With all things considered, a coin’s value is always going to be higher when it’s NATURALLY attractive. Historically, beautifully toned coins that are older garner a premium. It’s not just beauty that sets them apart but their "uniqueness".

However, as I have tried to point out before, we are interested in "value" for our dollars in the future should (when) the Dollar crash(es)? I doubt if a coin with toning is going to be worth more at that time. People should be able to use them to barter with and who cares what it looks like? A certain amount of value is attached to looking good. But, toning? I seriously doubt it will matter when buying food with it.
Personally, I prefer "blast white" as opposed to those which are toned.
|Blast white! My favorite.|
NEVER clean a coin. That can only reduce its value. By this I don't mean you shouldn't remove mud or dirt loosely on the surface if that ever happens. What I mean is do not dip a coin in Tarnex or use silver polish or rub it with a scratch pad!
I will dip a coin in rubbing alcohol and gently wipe it off then dip in distilled water after that for a rinse. Other than that - do not clean the coins!
Of course, if you buy a certified coin it will not have been cleaned - or the slab description will state that clearly. The experts can always tell and it will be labeled as "Cleaned" and the value goes into the crapper!
Unless the coin is extremely rare and holds some numismatic value despite someone drilling a hole in it - avoid these. Think melt value ONLY!
There are people repairing some of these coins - making them look almost as good as ones not damaged. Some people collect type sets and need a particular coin to complete a set of "every one" of something. The one missing could cost an arm and leg so, to complete their set they will purchase these repaired coins. Otherwise - avoid like ebola!
