Kemlin,
Wrong forum for this, but I think you'll need to take them to a knife dealer for an appraisal. Are these Remingtons or...? Is every model and variation included? The condition and age, etc. can make a big difference in value. That is difficult to do without actually seeing the collection in person. Just my $.02 worth.
