I just got a used Tejon and was going over my front yard again which is a 100 years old and found a 14k womens ring. Unbelievable. Anyone know how to get the best price for old gold jewelry? I had previously gone over the yard with a Cibola and then a Vaquero but with the Tejon's dual discriminators I had one set below foil and the other up to silver and it came in right at the foil mark exactly.
