Picked up several of these 1942 Japan 10 Pesos Military Notes. Anyone know what the "PD" and "PE" (in red) signify?
Maybe something about forgeries http://tomchao.com/as/jima.html Quote - "The American forgeries are known to have the following block letter codes: 50 Centavo bills - PA, PB, PE, PF, PG, PH and PI 1 Peso bills - PH 5 Peso bills - PD 10 Peso bills - PA, PB, and PC" Closed quote
They are just block letters. The P is for Philippines. The quote from Tom Chao's site only indicates what blocks appear on the US made counterfeits. Not all notes with those block combinations are counterfeits. Neither of these notes are counterfeits.
