Lapa Wrote:How about the 10K gold VDNKh?

Marc,
here are my numbers for the 10k gold VDNKh badge compared with its plated cousin:

10k gold version:
dia. 23.18 mm, thickness: 2.0 mm, weight: 8.4 gram, calculated density: 10 g/cm3

plated version:
dia. 23.08 mm, thickness: 2.2 mm, weight: 7.4 gram, calculated density: 7.4 g/cm3

(The weight is for the badge only. The calculated density, based on measured dimensions and weight, is low for both 10k gold and plated brass because the thickness is measured on the rim while the inner sections of the badge are thinner. The weight ratio is correct.)

Here are pictures of the two versions. The gold badge is on the left in both pictures.
