What does the mark 10KB and 10K-B mean when found on the back of a pin/medal with an enameled front? I dont want to misrepresent my item so would very much appreciate your help. Thanks, Judy

What does the mark 10KB mean

It

probably

means that the pin is made of 10 karat gold, and that KB is the trademark of the manufacturer. However, before listing it, to be absolutely sure, you should have it tested for 10 karat gold.

B would be the trademark, not KB. But there are a lot of makers who use B. It depends on the style of the letter and any other marks around it, such as a circle or diamond shape, etc.

I stand corrected! Owl is correct, as usual.. The letter B is probably the trademark, not KB. The letter K is part of the fineness mark (10K) which of course stands for Ten Karat gold, or 41.7% pure gold.

This mark means that the object is gold-plated, albeit to a high standard, so that the plating is not supposed to wear off easily. The B stands for bonded.
