After seeing many people being scammed by a paticular ebayer and almost being taken for fifty bucks myself, I wanted to put this short warning out here. Many of these insufficient ink errors being listed are just bleached notes made at home with common houshold cleaning products. Sellers have been getting away with misleading  auction titles and so forth. Before you bid on any of these notes, contact the seller and question these fist!! If the seller doesn't answer you, there's your first red flag. Check feeback and return policy. Most decent sellers offer a return policy on items, if not, theres red flag number 2. I have reported a number of these auctions. We need to look out for one another as well on ebay until policy can be updated to better protect buyers from misleading sellers like this.  Please contact me anytime if you have a question about these type of notes or anything else related to error notes or coins. If I can't help, I will point you out to the experts who can. Be carefull when buying !!!
