If you want to invest in Silver then open a brokerage account and invest in the iShares Silver Trust.

Do NOT buy stuff from TV channels selling coins. Overpriced and overhyped. For example, no collectors/investors are interested in colorized coins or gold or platinum layered coins. Pure junk!

Be wary of some coin dealers. They typically buy low and sell high. That’s why I like eBay for selling my coins.

Proof coins are one option for you. Buy them from the U S Mint, not a dealer. Some proof sets have risen in value but often it is a crap shoot.
Bullion coins are another option. Generally speaking, bullion coins are not directly available from the mint unless you’re a coin dealer. Remember Canada, Mexico, Australia, Great Britian, etc., all offer nice bullion coins.

There are a number of reputable coin dealers that could advise you in building a coin investment portfolio. Check for them in Coin World magazine.
