Are these really pulling this much money?

I bought one of the 501 model of this back in 2008.

Saw this on gunbroker today:

Are they really getting $1850 these days with 25 bids driving it up there??

If so I may have to let mine go. Is it cause its the old JM models made before the sale to Remington and a limited edition one? Mine has been a safe queen for all but one trip. Not one to hang on to stuff just cause but I remembered I had one the other day and went snooping for approx pricing to get an idea and watched that price keep going up?

Has anyone sold on gunbroker before? Is it a PITA?
