Help with these odd 1963 Topps cards
 

Please help identify these odd Topps 63s. This group of seven came from the same seller source as a lot

They seem to be printed on normal card stock. Their fronts are identical in picture, gloss, coloring...everything... to regular 63s.
There are some things about these that seem a bit different than other 63s.

The first strange thing about these cards are the extra white border on most of the seven. Almost as if they were cut from the edge of a full sheet of cards.

The second oddities are the backs. The black ink is very light or faded out. The color on the fronts is fine, but the backs are extremely light. There is no ripple or stain evidence of chemical or water damage.

The third odd part is the rough and wavy cuts of the edges.

All of these odd characteristics together lead me to believe that these are different than the regular 1963 Topps issue. Venezuelan? Some sort of proof? Cut from salesman sample sheet? Factory rejects?

Has anyone seen any 63s like this? Thanks

My first thought is that these came from a full sheet that had been stored with the back facing up and it faded over time. Then some kid probably decided that they wanted some of the cards and crudely cut them out.

Are they homemade?

I believe there was a find of some '63 partial sheets from a Topps dumpster dive at some point. I know someone with a partial 63 sheet that looks very washed out and he has indicated the seller had others in various configurations and condition. Those may not have been the original source of your cards but it is possible.
