Last Saturday mecum had a motorcycle auction. They had older vintage dual sport bikes, trials bikes. Besides older Honda cb ect. These bikes brought in good money. I didn’t see any Husqvarna for the time I watched. If your going to sell I think that’s the way to go. They even offered my old suzuki TS bikes these were dual sports with a 2t engine, oil injected. Most of the older bikes were between $1,000 to $3,500.
While, at that date/time they may have bought good money, Mecum or any car/bike Auctions are all the same, if two different people bidding want it bad enough they can drive the price some times thru the roof, so it may not be a good yard stick to gauge prices.
I saw it & thought the prices were reasonable except for a handful, like the JR50 that sold for $5000 (I think).
