What are pins people look for?

Hi everybody. I've been really interested to start an auction, but I want to make sure I am not wasting my time. I was wondering what kind of pins people (you guys) look for, and how to know if a pin would make a great auction. (If someone has already answered my question I apolagise and would love it if you could post a link. ) Thanks everyone.

Well, I'm looking specifically for Cleo the fish (PinPics #944), but in general, pins of underwater characters and different attractions.

Generally, if a pin has a very high trades/wants ratio, people will bid on it in an auction. (A lot more people "wanting" it versus "trading" it on PinPics.)

Also… Popular series like Beloved Tales, Designer pins, WDI Characters in Sorcerer Hats, and Pin Trader's Delights tend to do well, and limited edition pins of popular characters - characters from Frozen, Tangled, The Little Mermaid, Beauty and the Beast, Lion King, etc… Disney cats (Figaro, Dinah, Si & Am) are pretty popular right now too.

Best of luck on whatever you decide to auction!

Thank you so much for your help, I hope to get up and running my first auction soon.
