I've got this 1859 Colonial Bank of Canada $2. It is dated May 4th, 1859 and is signed by T. Hough. The strange thing about it is while it is signed and dated, it does not have a serial number. According to Canadacurrency.com, issued notes will be signed, dated and have a serial number. Non issued notes will have no date, signature or serial number. There is no mention of my combination. Can anyone tell me if I have an issued note? I did purchase it from a reputable dealer so I have no doubt of its authenticity.
