The most difficult large size United States type notes to classify by Friedberg number are the 1862-3 Legal Tender notes. Vexing is that the diagnostics used to discriminate between the multitudeof varieties are subtle and confusing. Adding to the confusion is that the ad hoc Friedberg numbers that were assigned to them are not in chronological order because many of those numbers wereassigned in the order in which the varieties were discovered.

Peter Huntoon worked with Doug Murray to develop a spreadsheet that lists every diagnostic for every issued variety in order to allow anyone to easily determine the correct Friedberg numberfor any of these notes.

Eventually this spreadsheet will be published with an article showing photos of the diagnostics. In the meantime those of you who work with these notes will find this spreadsheet to beself-explanatory and helpful.
