Mike Byers has published another excellent edition of his free Mint Error News Magazine. The current issue is cram-packed with more than 250 pages full of information and photos relating to error coins. As always, Al Levy's error coin price charts are fascinating. For instance, we learn that a blank Monroe Presidential Dollar with edge lettering sold for a whopping $20,000 on eBay! Another specimen of basically the same thing sold a little later for $1,791.67. Both were in NGC holders with no grade given (as is currently customary for NGC when grading blank planchets.)

Other pricing information I noted was that plain edge Washington Dollars (remember those?) are selling for an average of $43.85 raw on eBay, with graded specimens up to MS-64 running from about $60 to $90 depending on who slabbed it. MS-65 and 66's in PCGS and NGC holders were selling for about $80 to about $150.

I've had my eye on the Wisconsin Extra Leaf Quarters on eBay for awhile now, meaning to pick up a pair of them for my collection while prices are at their all-time lowest for these fascinating varieties. I pounced about 3 weeks ago, paying $118 for an MS-63 Low Leaf, and $124 for an MS-65 High Leaf. (I bought both coins raw, and these were the grades they subsequently earned from NGC.) According to the Mint Error News price charts, the average price for the raw Uncirculated High Leaf type is $190.66; Low Leaf is $116.81. Graded High Leaf coins, for PCGS and NGC MS-66 topped out at $446.33 and $378.67 respectively, and Low Leaf coins at $205.40 and $203.73 respectively. The Wisconsin High Leaf Quarter is rarer than the Low Leaf variety.

Lest I get too carried away with the error coin price charts in this issue of Mint Error News, let me just add that there are dozens of error types listed, from off-center coins to missing clad layers and practically everything in between. Did I mention that all this information is free?

Other topics covered in this month's issue include an amazing Walking Liberty Half Dollar that was struck twice on a coin blank meant for a Quarter! You can learn about the 2008 Silver Eagle Major Hub Variety, see a slightly different version of Fred Weinberg's Shanghai Mint Tour, and see scores of photos of error coins from the U.S. and around the world.

Not only does this ensure you'll always have a copy to read and reference in the future, it loads and pages faster when it's on your own hard drive (plus it's just good netiquette to save Mike Byers the extra bandwidth that repeated readings would cost him, not that he's ever said a word about it.)
