Not normally an item to get really enthusiastic about , but lately I notice dealer prices for all sizes, types, ages, materials, indicate increased demand, or scarcity. Vulnerable to scrap gold sale also. I bought a modern one at antique sale for scrap value. 31/2 oz. 33 real nuggets. 14k otherwise. Nuggets are not 24k. Colorado placer gold nuggets are as low as 17k. However, they have a little extra gem stone like value. The famous Soapy Smith of gold rush Alaska had a 3 pound nugget watch chain. This modern one was done by an Alaskan nugget jewelry maker. Not too new, some oxidation on 14k pieces. Very neat nondestructive gold soldering to nuggets. There are hundreds of years of plain and ornate watch chains made of a great variety of materials. I expect forum members could show some interesting chains, fobs, etc. Sometimes old watches come with chains that are a nicer item and more valuable than the watch.
