Here is one that went for $220 CAD in the march 27, 2014
Maresch auction.

It seems to me that in the last 30 years or so there is more and
more of this stuff coming out of the back door of these supposedly
Security Printers here in Canada.
Not much security there.

Many of these imperforate examples came from Ashton Potter who
no longer prints stamps for Canada but does for the USPS under
the name Ashton-Potter USA Ltd.
