are these tubular rims? the kind you glue the tire on? the freewheel (sprocket) is or in its day was a very nice one, and Campagnolo High Flange hubs are some what sought after.
I would suggest going to a shop and having the freewheel (FW) removed. if you simply remove the rims with the FW on, it is almost impossible to remove.
after doing that loosen all the spokes several turns until the wheels is wobly and then cut the spokes.
very clean the hubs may bring $40 to $60+ depending on how clean they are and the overall condition.
