The big problem coins have, apart from Kruggerands, is that u pay a premium to buy them, especially if they are mint…but if u want to sell in a hurry, you’ll only get melt value…that also happens at mkt tops.
At the famous 80’s top most coins sold for Melt only, as did thousands of tonnes of beautiful silver objects…that was a tragedy.
Kruggers have near zero premium….
