Monex is for speculating on “paper gold” with lots of leverage and fees. They are pushy; be very wary of dealing with them.
You can find old 90% silver coins at any coin shop or APMEX. To figure out the value of the silver content, check out coinflation.com.
Thanks for the link. As of Today it looks like 90% silver coins are worth 9 x face value. Think this is a better speculation than gold at this time as well as having some practical spending value for when things go bump in the night.
