can i sell foreign gold items such as cuff links etc in UK?

Answer 1

You can sell whatever you like on eBay .. (well, almost .. human organs are a no-no and it seems you can't sell your kids or other animals, although one guy did try to sell his Girlfriend a few years back :-) )

Of course HMRC (Inland Revenue & VAT guys) might become interested if you did it too often .. as would Customs & Excise (if they though you were importing them without paying Duty)

Answer 2

sell them on ebay why limit yourself to one place....
