Britannia Gold Coins. Cheapest way to buy and sell

Blue_Max

My interest in buying and selling Gold Britannia coins is purely as an investment.

Noticed that there are considerable differences in the buy and sell prices between the dealers.
Cost of inducements such as free delivery, free insurance, payment using a credit card, etc will inevitably be factored into their prices.

Are there any dealers who offer lower prices for payment by bank transfer and collection in person?
Which are the dealers with the lowest premium and spread?

Does anyone know about CelticGold AG, Frankfurt, Germany?
They claim to buy back at 100% of spot price?

I would be grateful for comments and advice from experienced members.
Thanks!

I think Hatton Garden are about the cheapest out there to buy:

Best sell price will be on ebay or a dedicated forum such as this one:

Most dealers usually offer around 2-3% under spot when buying
