Those little pale colored spots in the margins on banknotes
Can anyone tell me what those little colored spots are that one finds on banknotes form several countries? They appear in random positions, are about 1/16" in size and are always most noticable when they appear in the margin. They always seem to be in faint pastel hues. Are they a security feature? Some notes on which these dots appear: Brazil P151b, China P118Canada P185b, P75b, P77b, P84b, P87a, P93c, P93a, P93c, P94c. Thank you, Alwyn |

Thank you, Alwyn They serve the same purpose as the little colored fibers in USA banknote paper. They makes the paper harder to duplicate. -- ___________________________________________ ____ _______________ Regards, | |\ ____ | | | | |\ Michael G. Koerner May they | | | | | | rise again!

They are called planchettes and are an anti-counterfeiting security device. The American Bank Note Company has used them in banknote and stock certificate paper for decades. They have also been used on U. S. Military Payment Certificates. I've heard that some planchettes fluoresce when illuminated by a black light, but I've never tried it myself ... -- Ken Barr Numismatics P. O.
