I bought these the other day and wondered if there is any information as to what exactly they are. I bought three of them and they test positive for platinum. I realize that it is not a coin question, but I do not know where else to ask the question. Thanks for the patience. -Dan

What diagnostic test did you use to confirm platinum?
The eagle and wreath seem crude, but I don't really know anything about it. Looks like it's doubled a bit too. Share any info you dig up!
Well, just Love coins, period.
<< <i>It is 1"x 1" x 1/16" and weighs 10.2 grams. I showed it to a jeweler who tested it and said that it was platinum. >>
The density is not consistent with platinum. A perfectly 'square' block of 1x1x1/16 in = 1.0242 cubic cm, and with a weight of 10.2 g, that gives a density of 9.96 g/cubic cm.
But Pt has a density of 21.45 g/cm^3. So it surely isn't pure platinum.
Some other densities:
Silver = 10.5 g/cm^3
Gold = 19.32 g/cm^3
Palladium = 12.02 g/cm^3
Lead = 11.35 g/cm^3
Maybe it is silver with a Pt plating????

If it definitely is genuine platinum its still interesting.

I'll just say that I would've found it incredibly surprising that Germany would produce something without control marks of any kind (purity, "issuing" authority, mint, etc).. just not their style.
