Where are you finding values of non graded coins.
There are tons of websites that will give you a general price of a coin in circulated condition or at least the melt value.
Speaking of grading, for the gurus on here, is it worth trying to get some of my pre-1923 silver dollars graded? I've got a few that are in really nice shape, but it looks like its about $30 a coin to get them graded
I mean, the ungraded ones go for $30-40 on ebay and the graded ones, if they are in fine condition, go for $70... How is that worth the investment
