What is the value of handy gun?

If your question refers to the H&R Handy-Gun .410 PISTOL, and if it has a 10 inch barrel, depending on condition, these may be worth $500-$1500 IF the pistol has been registered as an AOW with the Federal BATF. If the pistol has not already BEEN registered, it cannot be, and would have no value- but possession of an unregistered one is a serous Federal crime. These are Class III firearms, and are treated in a similar manner to machineguns, short barreled shotguns, etc. IF it has been registered, the transfer fee is only $5. This is NOT the same weapon as the currently manufactured H&R Handi-Rifle.
