Good news! After suggesting, consulting and helping them, I have now received confirmation that one of Central London's biggest Gold & Silver dealer is now ready to accept bitcoin. Current buying limits are $100,000 a day, but soon it will be unlimited. You can either visit them in store, go online or call them.
Please note their new website will be ready by end of September. So they are only taking orders by bitcoin via phone or in store for now until the new website is ready in September.
UK & International buyers welcome but only UK delivery available for now, however they offer a storage service in their insured vaults for both UK and International buyers.
Next goal is to get them on the SysCoin Blockmarket.
