But luster is a very fragile thing. It is so fragile that if you were to put a piece of cloth over the end of your finger and then wipe the end of your finger across a portion of the coin, just a single pass, then much and possibly all of the luster in that area touched by the cloth would be destroyed - depending on the amount of pressure you used. Rub the entire coin with a cloth and it will look bright and shiny alright, but it will not have any luster left.

So hairlines can be present even though the coin was not harshly cleaned. For example, put an Unc coin down on a towel or a piece of felt, slide the coin across it even a short distance and the coin will have hairlines. Put an Unc coin down on a table, a counter top, a desk top, slide the coin across it even a short distance and the coin will have hairlines. You can even put hairlines on a coin with the end of your bare finger. This is because luster is very fragile.</p><p> </p><p>People think that just because a coin is made of metal and that metal is hard that it takes something harder than the metal to scratch or hairline the coin.

Most of you have seen this illustration that I use to explain luster - /\/\//\/\/. If luster were magnified big enough that's kind of what it would look like. It is caused by the metal flowing when the coin is struck. But at the top of those /\ 's (peaks) that you see the metal is very, very, thin.
