Noticed a nickel I had not checked for doubling. I have no idea when I put this in a flip but it had to be about 10 years ago. Anyway, it has both Class II and Class VI (distorted hub and distended hub) doubling. I recreated as close as possible the pics shown at Brians Nickels site. 10 years ago I assigned it AU55 but it is really a 50-53. Next photo shows the distorted best on the LU/PLURIBUS. ...and on UNUM, I added a close up of the distorted, doubled left leg/serif of the M. Best die marker: die scratch through UN/UNITED. Even the die scratch in RH small window. The last die marker shown in the listing has been obliterated on this coin. The hardest part here was dealing with light reflection and painstakingly adjusting for picture matching for comparison. I ended up using 5 different light sources. Admittedly, it is a minor doubling variety. What it illustrates is: if you get distracted by interruption (or life events, be that as it may) you can have things fall through the cracks. I have no idea what value it possesses but I do hope you enjoy the coin...Spark
