Before I got the link to open my guess was $1400 since it was NIB. I saw it's an anniversay model so I bet someone or two is happy.
I sold a Marlin 922M recently for $400 and it's a better gun IMO. There is nothing wrong with a dual extractor 10/22M with a bolt buffer. Most people don't realize how many parts on these don't interchange with the .22LR version. Even the stock is different. They also have a machined steel receiver instead of aluminum. They were made for 10 years but in lower numbers.
.22WMR is going for $0.40 per round face to face if you can find it. I'm sure it's more than that online. Retail is less in most cases but impossible to find in a brick and mortar store.
The above is how it is HERE, your area may differ.
Pass the gravy.
