So very new on getting some graded currency and recently acquired a 25 Cents First Issue Fractional Currency Fr#1282spnmf Narrow Margins Specimen. It took some asking around to understand why the front and back were two different notes. It was explained that these were used either as drafts in production or at banks as examples for anti counterfeiting. Cool first mystery solved for me. :-) Now how are specimens like this valued vs the actual notes? The one I have is graded 63 choice uncirculated. I see in Greysheet the FR# listed. Is that what you use as an estimate? I also have a Whitman Guidebook on currency 8th edition 2022 that list each face of the specimen individually. Would that be what you would use? Unlike my NGC coins there typically is a link to the estimated value. I did not find that on these, or an other actual note. I'm confused.
