Joe Offer..You might be surprised at how much gold teeth are worth.
No idea how old yours are but certainly the older the better. A friend of mine has just sold three gold teeth to a scrap company for £140....not bad eh?. They are still made of gold but the older, very yellow looking gold teeth are almost pure gold (high carat) and heavy. Might explain why a lot of old people walk round with their lower jaws hanging down....sorry just joking.
Suggest:- find a scrap gold dealer (or maybe check with as few first to see you get a fair price) and scrap 'em in.
Best wishes, Mike.
