I doubt that anyone will care right now, but one has to consider 20 years from now. Vintage collectors tend to look for the rarest items, and if there is a distinct difference between the first 350, and the second 500 produced, they'll care. Even more importantly, if there isn't a clear difference - that some of the second 500 are punched and some aren't and so some are indistinguishable from the party figures - they should be aware that someone selling an item on ebay as being from the first 350 could very well be lying.
