Rolex Cellini

[rolexkari]

I have just inherited a few rolex watches and am interested in selling a Rolex Geneve Cellini but I am having a hard time finding the same watch to determine a fair selling price. It is marked as 18k gold with raised roman numerals and a gold face. It is a model number 5112 with a serial number starting with N46.... It has a rolex genuine crocodile band. I do not have the box or paperwork but the watch is in mint condition.

Any information on what a fair offer from a dealer would be as well as how much I could expect to get selling it myself on a site like Ebay would be greatly appreciated.

Thanks
