Oklahoma notaphilist Roland Rollins published his latest catalogue, on modern banknote security features, this April.
Seven chapters highlight hundreds of both generic and proprietary security features, 90 per cent of which are illustrated with high-resolution images, according to Rollins.
The chapters include:
- “Printing Methods”;
- “Watermarks and Windows”;
- “Inks”;
- “Security Strips”;
- “Security Mask”;
- “Foil & Patch”;
- “Substrates”; and
- “Varnishes & Coatings.”
Among the nearly 40 firms with proprietary security features included in the 69-page book are the Ottawa-based Canadian Bank Note Company, Vancouver’s Nanotech and Britain’s De La Rue, the latter of which has designed 35 per cent of all the new banknotes issued in the past five years.
Rollins is selling the book for $25 (plus $6 for worldwide shipping).
