And what exactly is entailed?
I have never had a coin graded since I purchase all my coins pre-graded. But I think it costs for a low end coin about $15. But depending on the value of the coin the cost goes up. For example, a coin valued at $30k would cost more to grade than a coin valued at $250. You can check the grading companies for their exact pricing at PCGS or NCG. But there are a few other coin grading companies ICG and others but most quality coin collectors place higher value or respect for accuracy on PCGS or NCG. Just an opinion.
how much does it cost to get a twenty dollar gold coin graded by pcgs?
