No, just that my examples and the example Ricky shows have grunge in the small key and the inlays look yellowish; suggesting that they are uncleaned or even faded. Your example seems to be free of any grunge in the mold with a much whiter inlay. The example Charles illustrates on his site is noted as being Grey as well. All example I've had have always been Grey...

I have noticed thru the years that certain chips that have been cataloged as being grey were actually beige in preserved condition.
