I'm one of those weird collectors :P
Sadly I don't have any pony buying funds right now, or any real idea what G4 factory errors are worth, but I think this Fluttershy is awesome!
I get the impression that G4 factory errors like this are not worth any more than retail, and in most cases probably less than retail. There are a lot of flawed and "prototype" g4s out there and you'd need to find someone who is either into customizing that was going to wipe the cutie mark anyway or someone particularly into collecting oddities like this (which it seems there aren't many around anymore, but I could be mistaken) if you wanted to re-sell her.
Aww. Well, I've never seen a factory error of this type of pony before. people at the MLPTP said that she may be worth more because of it.

I'm not sure on value either. I'll probably list her on eBay and see if I get any bites.
The factory error is not going to have much, if any, impact on value. You could ask for a premium of $10 perhaps over retail. Especially because the package itself is designed to be opened, there is no way to verify that somebody has not removed the symbol for the purposes of making profit on a fraudulent factory error. So if you ever trade or sell it, your buyer has provenance that you purchased her that way but that is likely to eventually get lost. Collectors would buy her for the novelty but probably not be willing to spend much above and beyond normal resale value for her.
Her value might be more significant in trades with like-minded collectors because then you can trade error for error, see what I mean?
I personally love factory errors ponies because they are almost always 100% one of a kind!
Oh... that's too bad. (Also I think she was marked down at Big Lots, as at the Dollar Store these types of ponies tend to sell for $10 - $15 if I remember correctly).
I don't really have much interest in trading for errors, unless it's G1 and I'm sure most people wouldn't want to trade her for one of those.
