This will depend on the overall condition of the rifle in question?Since you did not include these details,I can say that a rifle in 60%-90% of its original condition remaining will bring between 230-450 dollars.Your rifle which is a post-64 model 100 rifle made in 1966 will reflect these prices.
For a air soft BB gun it's okay not powerful. For a regular BB gun "NO" that is not powerful at all. A Daisy Red Ryder BB rifle will fire around 325 FPS most new pellet Air Rifles will fire at least 1,000 FPS. A really good Air soft rifle will get around 500 FPS.

One just sold at auction for $230 Do you know if the rifle will handle a 22 short, or is it a specialy round for the gallery?
The Henry Lever action .22 is a great firearm. I have one myself, it is extremely accurate and smooth. The Henry rifle is also of very durable and well made. It should only decrease in value about twenty dollars from the original price once you buy it(250-230$).
