[QUOTE="bhp3rd, post: 823091, member: 16510"]I think all of you "miss" this one and bad. "Luster" is light back at you, reflected light from a source such as metal, mineral, polish, etc. Luster is an objects ability to absorb light and reflect it back - that is it. All struck coins that are finished, out of the dies, out of the mint have luster in mint state condition. Some great and some not so much and of course that is if in a light source. Some of you may be thinking well "that's a given" but it is not. There is no luster on any coin ever made in a completly dark room. It cannot happen just as a red table [B]is not RED[/B] in a completly dark room - it cannot be possible!!! Until there is a light source there is no red and no luster - I love this stuff!!! I think what you guys are needing to know is "what makes luster on a coin"? It is light refective properties of the coin when it leaves the dies! Everything effects the "luster" on a coin from the minting process forward each and everything that touches it, everything that passes over it, the air, the light, each and every day that goes by effects the luster - it can be no other way if you agree that the coin has the most luster it will ever have at the moment it is leaves the die. It is at that moment that it has it's most luster it will ever have naturally. What makes greater, or lesser luster on a mint state coins surface is detemined by planchet quality, die surface quality, pressure of strike, and luck. To say newly minted proofs don't have as much luster is not correct. If we don't learn the source of luster, which is light, how can we ever understand this? In regards to mint state coins and luster, "it is the mint state condition of a coin that has light relflective properties when exposed to a light source". That's all that luster is - it ain't magic you know, it ain't a coating, or a skin or anything else! Greater luster means greater ability to reflect light.[/QUOTE]
