I see objects such as yours, GuitarDTC, at many rummage/yard/garage sales. They are all common household items with minimal collector appeal. The step stool in its current condition is worth about $1. The sweeper about the same. The cookie gun somewhere between $3-10 if someone is looking for one to use. The hand crank grinder is a $10 item but many can be had for much less ($3-4).
If one looks at eBay for prices, one must look at sales of completed similar items over a period in time. Buy It Now prices mean nothing because many are priced too high and they just sit there for 30 days and get renewed for another 30 days, etc. Ebay prices are also a snapshot in time at what something sold for and not what something will sell for in the future. The market could get saturated or demand may increase/decrease. Prices go up and they go down.
