I found this item really interesting. So much so, that I bought it, thanks to your story. It arrived Friday. The devices are literally hanging to the rim by a metal thread. Yet, it doesn't appear to be flimsy. Imagine someone painstakingly cutting out the field with such accuracy. Imagine also someone cutting up an $800 coin to make this trinket. The coin had to have been remodeled in the 19th Century when the value of the labor was greater than the numismatic value of the coin. Thanks for including it in The E-Sylum.
