Good find Allcoinage, hope to find one like that someday. If you wish to grade it through PCGS it will cost $65 to grade a Mint Error coin plus $10 Handling Fee and $15 Return Shipping. This is in USD dollars also. It will take at least 4 months to grade an error coin, probably longer. Do not quote these figures ,i have a form I am reading off. There is a slight die clash on the reverse of your coin too. The back of the Queens head shows in an interupted line between front right claws. .
Thanks crabeater you have had some good ones-(error coins) too. Also thanks for pointing out reverse clash. I wonder how many die clashes that have been graded for this 1981 error. If none are on list then I will send in just to give me knowledge on next one I find.
