COIN COLLECTION 700+

Huge lot of coins for sale! My grandfather collected these over the course of 40 years and were passed down to me, but I do not have use for them. There are over 60+ coins in each plastic sleeve, for a total of about 450+ coins just in the coverings. There are also approximately another 200+ or so in ziplock baggies. Total collection is well over 700 coins! However, I have no idea how much any of them are worth. Please make me an offer.
