UsedSaddles.com is actually Lightning G Tack Shop located in Lagrangeville, NY. While they are a great tack shop and nice to deal with (I often go there myself)....they won't take in a plain flap saddle.You might want to try usedsaddles.com. Their saddles usually go through there fast. I believe you have to ship the saddle to them, then they sell it for you. I am not sure what % they take for consignment. I would say it is worth $500, it looks like it is in great shape. The used lynn palms at the consignment shop near me were going for $450-475 and not nearly as nice as yours. I personally prefer the plain flap.
