<prompt> Human: I turn 18 next week, and was notified that I will be getting 2 Gold Coins that my grandfather left for me to cash in, once I turned 18. I have no idea how much they will weigh, and I have no idea how to sell them. Any advice on how to safely sell them would be greatly appreciated. Edit I have not a clue of the weight, or kind. I will have to come back once I actually get my hands on them, and know what they are. Thank you for all the advice!  <response>: Become an expert on what it is you have. rcoins is a good idea.The less they are worth, the more it makes sense to hold as a family heirloom. If you are getting a 1787 Brasher Doubloon, It will make more sense to sell it and diversify.
