Hi all! I am going through a mixed envelope of 26's and 26a's and found this 26 with this star cancel. I have been looking for it online, but have not found anything yet. Does anyone have any info about this particular cancel? I thank you in advance.
I'm not an expert on cancels, but the color and impression do not look like an 1850s cork or boxwood cancel to me. The splotchy ink on the central star looks to me like a rubber cancel from the 1880s or later.
If you have an idea that a cancel has been added or altered, try holding it under a "black" or ultra-violet light source. Uneven inks will show quite plainly. Pen-shaped Diamond lights should also work
