[Game of Thrones Novels] You’re a peasant who finds a stack of ancient Gold Bars. The stack is as large as a Walmart. How can you cash in without people simply killing you and stealing it?

you’re a peasant.  no royalty or nobleman.  

how can you actually get credit for the gold without simply getting murdered?

Take one or two bars first. Go to a major city, pretend to be an investor from far away who moved here and wants to buy a business. Exchange your gold bar for a small business.

Over the next few years, take occasional trips to your stash, alone and disguised. Bring back a few at a time.

Buy a gold smelting kit (gold melts pretty easily, it is not too complicated a setup), and melt the new bars into more generic gold bars or trinkets.

Pretend that you earned all the gold through your business. Bu more stores and businesses so it's impossible for someone to track exactly where your money is coming from.

Do this for several years, expand your "business" empire and become the richest man in the city. To any observer you will seem like a shrewd businessman who made a fortune by investing into a variety of businesses.
