That's a pretty one! Nice micro engraving.
Normally, I advise collectors to steer clear of individual bond coupons, unless the bond is quite rare (like early U.S. Treasury bonds). The reason is this -- bonds often came with one or more pages
of 30 to 40 coupons, which would be clipped off by the company at six-month intervals as interest was paid. Many bond were sold or cancelled before all the coupons were used -- and few modern day dealers have taken to clipping these off themselves and selling them for a buck or two. With 60 or more coupons you can see why they might be tempted. Then they sell the coupon bonds, minus the coupons, which is cheating, imho. In the larger scripophily market there's little demand for these; most are bought as curiosities by collectors who don't really know what they are.
