Advise on selling collectibles or not

[ColRam425]

Hey so I've been thinking and I realized that I could sell off a lot of my assets to get my first Rolex. I happen to be a huge Star Wars nerd and have several limited and even signature edition Star Wars prop replicas (and 1 James Bond prop replica), made by Master Replicas and eFX (for those who know what they are), that I could collectively get quite a few thousand for. A part of me really wants to do this because Rolex is much more of a "big boy toy" in comparison, the only problem is I still love these lightsabers and helmets and I know if I sell them they will be incredibly difficult to reacquire later inline due to their highly limited nature, versus a Rolex which is pretty much always available in vast numbers. Any opinions out there on what I should do?
