I'm not really tuned in to identifying the fakes. Apparently some are obviously crappy print. Others are near perfect. Some can still be identified under UV light looking at the 'tagging' that the automated equipment sees. But even that they are getting near perfect. Not a new thing, but USPS made it way to easy with Forever stamps. Not even an issue of 'shelf life' for the fakes. They get more valuable every time they raise the cost of a stamp! This is part of the reason I don't even collect Forever stamps.
