If they are rare coins, you need to get them graded (I collect baseball cards and PSA grades all mine and its the standard on eBay).
Look up what is the best grading company on eBay by searching like coins and seeing who grades them. You will see the real value there. Condition means a lot.
If they aren't graded and dirty looking, get what you can.
If they arer't graded but high on eBay, get them graded then sell.
If they are just old, do what you need, not every old coin is worth a lot.
If this is too much work, just sell them if you don't wanna hold on to them, like double there cost (so 1800 silver dollars, 3600$)
Bottom line is, if you aren't getting enjoyment from them, and don't wanna go the collector route, pass them on, someone will love them
