Hi Goku, 
Your cels are really nice but you must have been 
pricing them what they were worth 4-5 years ago. 
now sailor moon cels like the ones you have are 
not worth 300+. I think you should go through 
your gallery and re-check then with other dealers 
and ebay or rinkya and see what the current rates 
are.  Thank you
