It depends how much you have and what type of coins you have. Are they collector coins (as in, high grades, key dates, rare coins) or are they junk silver coins (as in, worn silver quarters from the 40s, silver dimes from the 50s, etc.). If they are collector coins, it is better to sell to a reputable dealer. If they are junk silver coins craigslist and eBay are your friends, but dealers and jewelery stores will usually buy them too.
