Old 3 Speed Shimano internal Hub wheel set

Whats up guys,

Recently one of my bike collector friends sold me a whole bunch of his old parts, and among which were a set of Shimano 20" wheels with a 3 speed internal hub. I've only been part of the bike collecting hobby for a year give or take now, but I do know that these wheels are quite rare, and collectors are always looking for these hubs. I  can include some pictures once I'm done restoring them, but these wheels are in great shape for their age. i removed all the surface rust on only the back rim so far, but the front rim was in better shape so I imagine it wont be harder to make that one good as new again. The back wheel is not true, it is slightly off. I'm not going to bother truing it myself because....I'll be honest, I suck at it. The front wheel is almost perfect, its about 95% true. The reason I'd like to sell is I know a bike collector could really benefit with these, and I'm putting Skyway wheels on my mustang real soon and wont have a need for these. The rear wheel will need a pushrod and bell crank. If you go on ebay there are a whole bunch of NOS ones for pretty cheap. How much do you guys think I could make out of these? I'd be willing to sell to one of you if a reasonable offer is made. Like I said, if pictures are needed just ask and Ill take some asap.
