[QUOTE="GDJMSP, post: 2350961, member: 112"]iPen - The question in your title is one thing, the questions you are asking in your posts are an entirely different thing. Proof coins have cartwheel luster just like business strikes do, so of course Proof-Like coins also have cartwheel luster. There is a distinct difference in the cartwheel though, the difference lies in [U]the width of the band of reflection[/U] that we can see with our eyes when the coin is rotated under a light. On a Proof that band is very narrow, more focused because of the mirrored fields. On a business strike the band is much wider because of the rougher, more textured surface of the fields. Think of it like this. On a business strike the flow lines, if greatly magnified look something like this - /\/\/\/\/\/\ On a Proof, (and I can't draw it with a keyboard) those would be much, much, closer together, but they would still be there. And it is those lines that reflect and refract the light and create the cartwheel effect that we see when the coin is rotated under the light. Wide peaks and valleys (business strike) create a wide band of reflection. Narrow peaks and valleys (Proof) create a narrow band of reflection. On Proof-Like coins the peaks and valleys are narrower than the business strike, but not as narrow as those of the Proof. If you were take a business strike, a Proof-Like, and a Proof, and rotate each of them under a light one after the other, you would see the same cartwheel effect on all 3, with each having a narrower cartwheel than the others, respectively. To determine if a coin is Proof-Like or not, well that's a matter of degree. It's kind of hard to explain with words but the Proof-Like has some of the characteristics of a business strike and some of a Proof - but's neither one nor the other, it lies somewhere in between. To say one is or one isn't, is really a question of experience. It's kind of like the difference between Cameo and Deep Cameo.
