There were three models of the AMT (Arcadia Machine and Tool Co) Automag II .22 magnum pistol. You do not specify which of three barrel lengths you have or the condition. The original AMT automag II in good condition is currently selling for $300 to $440. The High Standard Company has taken over manufacturing the Automag II. See the link below. The current MSRP is $695.00. The price in 1988 from AMT, about the time your gun was made, was $325.00 This particular gun is prone to jaming due to the gas locked system, and rough 12 hole gas system, and cannot use certain ammunition factory loaded with ball powder. Anyway, that is probably more information than you wanted.
it can range from a price of 10,000 to up to 1$
Which version... the centerfire model or the .22 rimfire model? There is no serial number on the rimfire model 55. It was made prior to the requirement in 1968.
the Marlin Model 57M (.22 Magnum) was produced from 1959 to 1969. Since most .22 rimfire rifles had no serial numbers prior to the Gun Control Act of 1968, it would have been produced prior to 1968 if it has no serial number.
You will have to call Browning with the serial number.
