[QUOTE="GDJMSP, post: 107711, member: 112"]Since they are both made of the same alloy - I doubt it has anything to do with chemical makeup. I have always attributed it to the fact that Morgans have a different surface finish than Peace dollars. The surface of a Peace dollar is smoother than that of a Morgan which is what makes the Morgan appear more lustrous - it really isn't, it's just a different luster. The luster is the result of the flow lines on the surface of the coin. And if you examine a Peace and a Morgan under high magnification you will see the surface of the Morgan is rougher than that of the Peace. I attribute this to the die preparation and improvements in technology. I believe that the surface of the dies ( which is what creates the flow lines ) for the Peace were polished smoother than the Morgan. For example - a simple illustration I have used before to demonstrate luster - this is what the surface of a Morgan looks like - [SIZE=5]/\/\/\/\/\/\ [/SIZE] This is what the surface of a Peace looks like - [SIZE=1]/\/\/\/\/\/\/\/\[/SIZE] Because the flow lines on a Morgan are deeper than the flow lines on a Peace it exposes more surface area of the silver to the air. Thus the surface of a Morgan tones more readily and deeper than a Peace does. Anyway - that's my simple explanation for it.[/QUOTE]
