These sound like National Bank Notes. They were issued in three series: The first series was issued from 1902-1908. The seal on the front of these would be red. These are apparently quite scarce. My ten year old Friedman guide said they were worth from $400-550 in VF condition, back in 1998.
The second series was issued from 1908-1916. This series had a blue seal, and will have the dates "1902-1908" on the reverse of the note near the center. Most of the notes in the second series listed at $85 in VF condition. The Napier-Thompson signature combination listed at $125 in VF, while the Teehee-Burke listed at $175 in VF. Again, these values are from 1998.
The third series was issued from 1916-1929. These have the blue seal on the front, but do NOT have the dates "1902-1908" on the reverse. Most of the third series notes listed at $80 in VF condition, except the Napier-Thompson which listed at $150in VF, and three different signature combinations signed by Wood listed for $250, $500, and "rare" in VF.
Since the guide book is ten years old, you can add at least 50% to each value, probably more like 100%, or even more to each of the values!
