Sold a Centenary in .22 for £450 posted (had all the extras: scope, mounts, sling, bag, cert, oil bottle, pellets, targets and badge), so as there were roughly 750/775 made in .22, and only (again roughly) 250/225 made in .177, imo I guess you should be looking at £500 plus post for yours . If you choose to sell however, please remember to start a separate sales thread (see stickies ). Atb Gareth.
