Iconic Canadian Chartered Bank Note — Standard Bank 1891 $5
This is one of the most iconic and popular designs from the Standard Bank of Canada, founded in 1876, and operated until it's merger with the Canadian Bank of Commerce in 1928. This design came in four flavours, three of which are very rare.
The first type had blue and yellow face tints and a brown back. A single known example resides in the National Currency Collection. Luckily, "SPECIMEN" notes of this variety do exist as shown here.
The second type had green and yellow face tints with a green back. Only two known examples exist, one of which is in the NCC. The one shown here, the only one available to collectors, is reportedly the better of the two.
The third type had red and yellow face tints with a green back. Only two known examples exist as well, with both of these being in significantly worse condition, both having been found in the same decaying hoard. This is possibly the worse condition note I've ever handled that also holds the title of "finest known".
The fourth and "common" type had red and yellow face tints with a red back. While certainly more common than the other three varieties, it is still quite difficult to obtain in any kind of decent grade. The example shown here is, as far as I've seen and handled, the finest available by quite a wide margin. The iconic status of the design along with its popularity make this a trophy note in its own right.
