Just Going Through Some Canada Stamps Have I Found An Error?

Hi I've been going through some of my Canada stamps found these two. Is It an error or has the gold just worn off as I can see the black outline of the word canada at the right angle.
Would love some opinions.
Thanks.

This belongs in the Canadian stamps and covers section.

There is no listing for such a variety. The stamp looks badly creased also. Maybe it is from rubbing ? Do you see scratches ?

Got up today and looked under a microscope with my mate and we can now both see faint bits of gold so must have rubbed off but strangely no scratches or wear around or on the area.

I can't speak for the alleged "color missing" issue, but maybe a slightly enlarged scan of the stamps in the proper orientation might help:

Here is another one missing the 'Canada' and denomination printing, with the correct one on the left.

This is a forgery, with the printing removed (V.G. Greene certified).

I don't know the specifics of the process, but I know it is possible to remove the gold printing somehow. There have been a number of issues worldwide that have been sold as printing errors that turned out to be fakes having had the gold printing removed.

Does same rationale apply to silver printing removal?

I have two of the Autumn Leafs stamps with the silver removed. Both are VFNH, with the gum looking PO fresh. So whatever process is used, it does not create any noticeable damage to the stamp. Also, to the naked eye you cannot see any of the prior silver printing. It makes me wonder what V.G. Greene uses to determine it authenticity.

This experience resulted in me not purchasing any 'missing' printing stamps without a certificate from a renowned organization.
