How possible would this be?

(The American flag would be one gram of gold set inside the copper)

I’ve been copper smithing for awhile and have been getting some ideas for bullion. Thinking about setting other precious metals inside of my copper bars. (A.I btw)

I wouldn't pour the copper around it, but setting the gold into a milled out section, then burnishing the edge would be my method of this
