Selling old gold caps in London
My London-based granny absolutely used to love her gold bridge work as well as caps. She used to say this made her look 
That’s right people with the price of gold now touching the sky around £600 per ounce; the price of reclaimed gold from fillings, crowns and cap has really touched the sky. Gold crowns, fillings and bridgework are preferably made of 16-karat gold, which is alloyed with special metal like silver, zinc and copper. These alloys are responsible for making gold dental work soft enough for the dental technician to work with but hard enough to hold pressure during biting. A single gold crown is usually made with one-tenth of an ounce of 16-karat gold, which can cost around £40 to £50. Much heavier pieces like the ones which I hauled to the goldsmith can cost mush higher! So go ahead get your old dental pieces to the dentist for an evaluation. You never know what you could get for them!
