I just had a blast from the past when I saw this on eBay-- This type and other similarly crude coins began turning up in uncleaned coin lots in 2003. At first, some people thought that maybe these were "barbs" until it was noticed that they are all die matched. So a note of caution, as some collectors don't think that common LRB's are faked. Dane has a page with more info including other types-- http://www.catbikes.ch/coinstuff/coins-fakes.htm
I bought maybe 100-200 uncleaneds in 2004. I don't think I had luck with a single one, although they seemed to be genuine uncleaneds. I used the 'best practices' I could find at the time, olive oil, etc. Just a slimy mess.
Usually, the lettering on imitations is more garbled and difficult/impossible to read than on the official issues...not the opposite!
Yeah, these would have been a major upgrade to mine. At least they would have had comic value. That's quite interesting how fakes have progressed.
