Goldbug ping.
I read somewhere that “junk silver” is a good way to secure fractional silver. It consists of coinage containing percentages of silver and they come in large bags. As far as gold goes, you might want to check reputable dealers like one I researched named Golden Eagle Coins located in Laurel MD. They have a very loyal online customer base. Very nice people and they ship out faster than any of the large named corporations.
