G1 Quick question!

[Diamond]

Need some fast help and yes I know long time no see.  How does one tell the difference between a mail order CP and a regular one.  I have a dark and a light Cotton Candy and thought I remembered something about the one being the mail order.  Many thanks. 

Sorry picture was on my phone so from FB link -

I might be wrong but I believe a lot of it is by color variation, but if I remember correctly Cotton Candy makes things a lot trickier as she seems to have more variations than others, just in my sister's and my collection, not including Nirvanas I believe we have 2 or 3 eye colors and like four different body colors, hopefully someone else will be able to help you identify them better, but I know with her at least it isn't an easy  task.
