MORE ON ANTI-COUNTERFEITING TOOLS

Regarding the items in last week's issue relating to anti-counterfeiting
tools and techniques, Joe Boling writes: "I have a Spuriscope. R. M. Smythe
auctioned two of them in their Memphis 2005 sale - I bought one. It depends
on the relationship of face check letters to the position of the note on the
sheet and the concomitant serial number that is printed on the note in that
position. It no longer works, as the required correlations no longer exist.

"Regarding security features in Japanese notes, they may be pushing only
the watermark for the general public, but the notes are loaded with security
features, including: microprinting, iridescent and luminescent inks, two
kinds of latent image, a second watermark, and a hologram on the two
high-denomination notes."
