How can I tell how old a ring is?

A ring with no marks can still be gold; a jeweller can test it. Plated rings often show base metal where the plating has worn.

In many places a recently lost ring is lost property, and the law expects finders to try to return it or hand it in.

How do I know if my find is worth anything? Identify it first: value depends on exactly what it is, its date, condition and rarity. Gold and silver items are worth at least their metal content. For coins and jewellery a reputable dealer or auction house can value them; archaeological finds can be recorded by a museum or finds liaison officer.

Can I keep treasure if I find it? It depends on where you find it. On private land, finds generally belong to the landowner unless you agree otherwise. On US federal land, archaeological objects over 100 years old cannot be removed without a permit. In England and Wales, finds that legally count as treasure must be reported to the coroner and may be acquired by a museum, with a reward shared between finder and landowner.
