Floyd Roman plugs

[roym]

I was remodeling a bathroom in a customer's home and noticed several rods and reels hanging in the basement. The homeowner, an elderly gentleman, offered to give me a bunch of lures including a Floyd Roman Dart and Dart, a Sizzler, and a Lil Sandee (all in original boxes). I thanked him and told him they were too valuable and he should really have one of his adult children take them but he said they didn't want them. I then told him they were too valuable to just give away and I couldn't take advantage of his generosity. They were in the original boxes, the trebles were rusted but the finish looked good. I really would have been tempted if he had a Nike as this will be the next plug I make in the Fall. Any ranges on the value of these three plugs? I make plugs to fish but do not collect but absolutely admire the work of those that preceeded us. Can anybody give me an approximate value of these plugs so I can inform him of their value to a collecter? Thanks
