2000.While the previous answer states the year 2000,My research indicates that your Marlin model 883ss was made in the year 1994.You take the first 2 numbers of your serial number and subtract that from 2000.Hence 2000-06=1994.
These rifles were made from 1993-2003 by marlin.
Between 75-120 dollars,depending on overall condition of your .22cal rifle.
I assume you're talking Marlin here.In 100% condition I would only guess oh-------- maybe,$375
Due to the current lack of availability, you best shoot whatever you can find. Beyond that, CCI and Wolf make fine ammunition.
