Sorry to hear about your personal experience with your dad's coin collection Cecil. Probably the best way to get a true value of your dads coins is to check sold ebay auctions of comparable coins. Dealers might be the easiest and quickest way to sell but if you want to get a more accurate price value for your coins you'll have to sell to the people the dealers sell to - although that will likely mean some added selling costs for you unless you find a buyer someplace like Craigslist.
The coin collection that dreamboxvip found is worth considerably more than fv. And it looks like this collection was meticulously put together by some collector also only to have someone else carelessly and quite ignorantly just cash it in at fv at the nearest bank. The silver war nickels right now are worth about $1.20 each and could easily be sold quickly just about anywhere , even for free on CL where I live for at least $1 each which is 20 x fv. And the buffalos look to be in really nice condition and are very popular with collectors and could be sold for around $1 or so each also (depending on date and condition). The intrinsic silver value of the '65 Canadian dimes right now are worth about $1.28 each which is almost 13 x fv. And the key date '50D nickels are probably worth at least $5 or so each depending on condition which is 100 x fv.
Even the most dishonest dealer should be able to offer at least half of the true value of the buffalos coins and '50D's and any semi-key dates and at least 75% of the intrinsic value for the silver coins which is still considerably more than just fv. But whoever had them last was obviously unknowledgeable and probably very disinterested in the coin collection they had acquired (however that may have been) and just wanted the quick cash from the bank. So dreamboxvip definitely made a huge score and profited hundred's of dollars in intrinsic silver and collectable clad coin value from someone else's loss.
Ignorance is bliss but it can also be quite costly as it was for someone in this case. But if the someone in this case didn't have any more interest and respect of someone else's coin collection that they had acquired then to just dump them at a bank for fv then I think they probably got just what they deserved and dreamboxvip was in the right place at the right time to profit from their ignorance and carelessness.
H$H!
