On the one hand, the purist wanna be coin collector in me said, "Eeeek--they defaced those marvelous coins!"
On the other hand, "Wow, what craftsmen, can you imagine the tlc they had to put into those pieces?"
I think I really like the jewelry and appreciate the talents of the craftsmen but it's not aluminum cans that need recycled--the coins are already valuable. Maybe if they made things out of trash instead of treasure?
I, too, am a sinner, or a least one of my ancestors was. My mother gave me a bracelet she received as a gift when she was a child. It has a dozen or more world wide coins with a single hole punch in them so they can hang from the bracelet as charms. I adore it and wouldn't sell it for a million dollars (or would I?

)
