I bought a Remington 511-X (1964) this week at a pawn shop. I paid $175. There was a copy of a gun Blue Book on the counter, maybe not the latest edition, but it listed the 5411-X at about $175 for 80% finish, IIRC.
In Excellent to MINT (LIKE NEW) $150-200. They are an older inexpensive plinker.
Google Remington scoremaster model 511. Several websites have information on this .22 firearm.
I don't believe the Remington 512, 511 or 510 have serial numbers

check the date code stamped on the barrel. Remington Society of America, Manufactured Date link has the details.
It means that the stamp is worth 511 dollars. kthanks
The 511 is a very desirable 22 rifle, discontinued in 1962 or 63. If the rifel is in perfect condition, as new, and is a standard model, with the original Remington marked clip it is worth between $175 to $225. The value of used firearms is greatly dependent upon condition and the 511 is no exception. As the condition goes down so does the value. I have bought 511s in not so good shape just for parts at about $50. Ed
