I have a guy i work with that is going to take his grandmas coin collection to a dealer to get an estimate....he is going to let me look at it first to see if there is anything i might be interested in.....he asked me to roughly grade and price everything for him so he can get a general idea of what the dealer might offer him...there is between 30-40 dollar face value he thinks 8 peace dollars a few walkers and franklins,a bunch of kennedys and rest mercs and washingtons.I can get a rough value for him out of redbook but boes anyone know about what percentage of book value a dealer will offer.I told him with there profit margin to not expect much unless he has some key dates which it doesnt sound like.he thinks an uncle went thru them a few years ago and took what he wanted....any insight or opinions would be appreciated...hh jon
