coin dealer

I was joking with hubby that I plan to become coin dealer once I retire from work. This is because gold coin prices getting higher and higher now, I don't think I have the extra cash to own it, so I better become the agent and count the coin index for my customer. Well, I better start doing my homework now, study and analyze how to invest into gold or silver coins. Hubby did not object my idea but he suggest me better study in share market since he has knowledge in this field and he is able to guide and teach me too. Too bad, I am not interested in share market at all. I know I could take some time to learn it, but I still do not have the energy to go and pick it up. Ermm..other than coin dealer, what else can I do as side business?
