Suspect Scott #314 and #315
I found these two in a large box lot that I had bought at
auction some time ago. At first blush they look like Scott #314 and
#315 (CV$15.00 and $900). Now the chances of finding a #314 in a mixed lot
is pretty good but to find a #315 in such a lot would be astronomical -
you'd have a better chance winning the lottery. So I knew right then that
I should look closer at the both of them to see if they were genuine or
Lets take a closer look at the edges to see if there is
any evidence of trimmed perforations. First the Scott #314.
As you can see there are a number of perforation divots
left behind when the stamp was trimmed. Next lets look at the #315.
Again there are a number of perforation divots left behind
when the stamp was trimmed.
In conclusion these two stamps are nothing more than Scott
#300 and #304 trimmed down to resemble Scott # 314 and #315
