value of Marlin .22 Glenfield model 60

Looking for a manufacture date and approximate value s/n 24288149. Two letter code on barrel near receiver is "JM".

Firearm is in excellent condition

hello jerry,,your marlin has a used value of between 80-135 if really clean ,,dates of manufacture are not specific but were first made in 1960 and are still in production to date,,good little semis and not many problems with them other than some ammo isn't really powerful enough for the action to cycle properly,,and some time may cause feeding problems..

hello again ,,i found some dating codes online and if your marlin has a letter before the serial number its a post 1969 model and i may be able to give you the year of manufacture,,if not it was pre 69

I have supposedly my dad's Glenfield Mod 60 22LR
serial number 21446157. Could you tell me the year of this rifle?
Thank You

marlin made so many of these inexpencive 22 auto loaders there aren't any records of individual years of production that i'm aware of ,,it was introduced in 1982 and is still in production today ,,value of it would be as listed above ,,for a newer model or older model alike..
