He is certainly honest enough to have declared that the coin had re-surfaced, but as he presumably wanted to put it on his website -which he has done- and may want to sell it on in the future, it’s not really that remarkable, just normal behaviour. What is strange is that he is trying to impose on Richard conditions to be fulfilled before he will complete his side of the contract, which he has no right to do. He is not in any way a beneficiary of the insurance, and carries no liability in its legal settlement. The RM makes it clear that only one party can benefit from the claim, and Richard has done that. The responsibility to repay the compensation is Richards alone, and of no interest to the purchaser.
I am really amazed that what should be a good news story has become an issue causing stress to the party who has behaved entirely openly and correctly in his management of this transaction. It is so disheartening.
