I have seen Li'l Bears go from $50.00 to $150.00 depending on the year, the condition, and who is bidding on them and how bad they want it.
That is a great starter bow for a kid. If I were you I would keep it passing around the family to get the young'uns started. An '80's model would not be that collectible, in my opinion, but it is a great bow to have around.
