homer has a specially made set by Jamie. It has some special features which take it to a new level, which is saying a lot considering what a high level schoolcraft coins are as is. I have a morgan set and they are a piece of art. As for your question about the color, its called Patina, or softening the coins. Jamie will make the coins, or rather find coins that fit your description and alter them, exactly as you want them as far as color, softness and other features. Yeah they aren't cheap, but you get what you pay for and i have never once regretted spending the money for my set. any more information needed just ask, as for the stuck shell, it may be a result of a dent in the shell itself, i would inspect all the coins and the shell itself and double check for anything suspicious.
