I rarely see any offered at auction. Are they more rare than a gold sticker?
I believe that they say the coin is overgraded? I wonder if Collecting these might pay off in the long run. Anybody collecting them? Own any? Or previously??
Some of my coins might qualify, not sure???

Thanks
I haven't heard anything else about them since 2010?? I think some misinformation mislead me. Look up black or blue stickers on the internet? See what you find.
I guess that they do not exist.
