bullion is a valuable thing to have
gold or silver coins are the official money of a country
so usually less counterfeiting because of the gov laws
coins are more easily identified and have strict content that everyone knows
coins are legal tender
a one ounce gold eagle has a value of $50 by the gov
if you sell something for one gold eagle you could claim you only got $50
you might want to give someone some of your money before you die
so maybe give them say $1000
do the math
