I would like to thank people on responding on my first post. Some of the advice is useful. Previously I have purchased & sold sovereigns . They sold at scrap price below spot price. It did not excite me. I am only investing in 24ct Gold . So Ounce coins such as Britania, Maple leaf, Australian Kangaroo, Austrian Philmoric mints or any 24ct bars are my choice of items.
I am a tax paying citizen and have receipts of Vehicles bought & sold but who on earth would want to be under investigation of Hmrc ? Its a daunting investigation where all your bank accounts could be frozen until it’s completed. Also my bank charges 4 % cash handling fee.
@Paul many of those dealers you listed do not accept cash at all, I called Baird , Gerrads, Atkinsons, and few more. And some of them do not offer counter service. Ideally I would like walkin counter service.
Those dealers who can provide me invoice online with their bank account number can also be a good option. I am happy to keep transactions under £5000.
@davegolddigger my dear Dvla does not care if you buy/sell and dealers accepts £millions cash in car trading even with zero income proof. You can walk into car dealerships with unlimited amounts of cash and they will kiss your hands. You go to a Gold shop with over £10K . They will show you the door. They are completely different industries. Its the Hmrc all gold dealerships are afraid off. Lets not divert the topic elsewhere
Much respect to all posters keep your advice coming:
