I have double planchet clipped 50 piece and I am curious of the value. I have had these for several years and find them an oddity in to keep in my collection.
Also, how far off centre would you consider it to be an error. I always see small offsets in coins and occasionally a large one, as one side of the rim is half the width on the other.
Cheers, Vaxx
