Sell the pre 1982.5 pennies by weight on eBay, you can send these in a USPS small flat rate priority mail box, you can typically get $3-ish per pound. Separate out the Indian head ones and sell them by the roll on eBay. Sell the 90% silver coinage by face value on eBay. There is a FV multiplier that people will use to figure out the total silver content and value.
You will actually get much better profits selling on eBay vs. a local coin shop in my experience.
