when I have bought gold online aka Sovereigns to the value of £1100 (a few coins back in 2017) Bullion Dealer (A large known Bullion Dealer)  has posted them to me using Royal Mail Special Delivery with the correct level of insurance.

When I have sold the same over the years on eBay I have also use Royal Mail Special Delivery with correct level of insurance (max £2,500).

If I was to sell say a 1/2 Sovereign for approx £450 (or current value) I would have to use eBay simple delivery that I would expect use Royal Mail special delivery option.

So for gold I would expect eBay would cover a lost parcel with a gold coin in it?

Thanks for the replies.
