Are my fish coy or goldfish?

I have a large pond with coy and goldfish happily living together, last year they spawned and we rescued a number of teeny fish which have now grown into multi coloured fish about three inches long. How can I tell if they are baby coy or baby goldfish?
We have rescued a lot of teeny ones again this year and we are curious to know which they are. The colours of all the fish are similar so we just dont know.
Answers:
Koi and goldfish will crossbreed, so your babies could be koi, goldfish or crosses (mutts) I think the crosses look sharkey
believe it or not, but KOI and gold fish are about the same fish!!
I'm not a fish expert, but maybe they crossbred
Lol are they made of gold?
koi
Koi usually have a little mustache like thing going on.like a whisker on either side of their mouths.
Koi should have whiskers like cat fish do. One on each side, but shorter than cat fish one.
koi have whiskers on the side of their mouth hanging down gold fish don't
Both are members of the carp family with similar color combo's. my guess would be size. Wait and see how big they get as domesticated goldfish usually max out at 1ft and Koi 3 ft if a good bloodline. Also. goldfish varieties have different tail and eye configurations whereas Koi do not.
