Jean, it really varies. Depends on the region and the frequency & actual sale price (vs. asking price) of similar machine/transactions in a given area. Sorta like “comparables” in real estate.
Photos would certainly help this community assess the characteristics of your iH Cub, so probably worth your time to dig it out of storage for some pictures. Think: front & back, plus quartering-to and quartering-away angles of both sides, and perhaps a picture or two of the engine compartment.
Like they say, pictures can be worth thousands of words of description.
Some of our most prevalent members are located in the upper Midwest and might be able to comment on recent comparables based on looking for transactions nearer you. But again, pictures would sure help.
From what bits you’ve shared, it sounds somewhat similar to machines that have sold in the KC region going for anywhere from $75 (rough, non-running) on up to a few hundred bucks (functional, working, fair shape). BROAD range.
It would need to be in good working order, good physical condition, and feature-bearing to reach or exceed (perceived/actual) value much higher than that; again largely dictated by the market in your locale/region and ultimately by the number (and enthusiasm!) of prospective buyers who materialize.
Best wishes.
