I just came across this thread. You are wanting appraisals of value for the purpose of selling. However, I think it may be wise (and you might find it's fun) to learn about Loveless knives and how your two fit into the historical spectrum. Learn about how the market has been through the past couple of decades and get an idea of how it is now. Have professional, high quality, detailed pictures taken for starters. There are many experts of Loveless knives out there, but you have to deal with experts you can trust. There may be true expertise on his end, but that says nothing about his character or motivations. Stick with the names you've been given on Bladeforums. You'll get an idea of value.
Here's where I interject my personal opinion of things. Most people, myself included, will tell you that market value is set by supply, demand and condition. That is true, however, "demand" is conditional on the other two and is the one factor that you need to decide how you're going to approach. If it turns out that your knives are old, nice, but pretty common and standard Lovelesses from the era, I would price them to appeal to a suitable percentage of collectors out there and I would probably go through a high profile dealer who can reach most of the market and pay him the agreed commission. I would do this so that the knives would sell, not sit, reasonable price, move on, life is short, all is good. The dealer needs to know that this is your requirement and needs to make it happen.
IF your knives are highly significant Lovelesses, you do not want to target a significant percentage of collectors. I would price the knives so that they only appeal to the extreme minority of collectors who desire to build the finest Loveless collections in the world. They are out there and will pay more to own the rarest and most significant. Retail value in today's market is secondary to some of these folks. You sometimes hear people say "the market is soft". Trust me, the market for the very finest of anything is never soft. People say "there's not as much money out there". Well, you only need one buyer (he will buy both knives in they're in the category we're talking about) and if he's one of the top Loveless collectors in the world, he still has a little money left.
I'm sure that we all have horror stories about one or more of the shippers and our own reservations. I have had insurance claims before but fortunately they were with low end knives and nothing of this value. 
Maybe I am being overly skeptical but I would be tempted to be sure with these.
