Price Check- GS Gyarados PSA 10 English

I have a gyarados at psa currently and am anticipating it grading a 10. I’m trying to figure out what price is fair to ask for it should it receive the 10. I saw that two have sold on ebay. one for 1400$~ and one for 1700$~. There is only one currently listed on ebay and BIN is 2400$ and open to offers. With only 1 other one on the open market, I believe I should be able to shoot towards that 1700$ range, but I want to make sure I’m being fair with my prices. Thanks for any suggestions!
