ODD SNES Game Labels

[Space Fury]

At an auction house in California, I won 162 Super Nintendo cartridges that were described as being blank.
The picture of the box of carts showed several carts, all of which had no labels, so I took a shot something could be in there.

When I received the box of carts, I found samples like this in there in yellowed and dirty plastic cartridge bags.

I don't know what these are. The ones marked as blank, DO work as do all but 15 of the ones I bought.
There are other games in the box that have no labels at all.

I played most of the games pretty far through, so I know they are complete.

Back of each cart is embossed with the care info instead of having a label.

Please let me know if you or anyone else in the community have seen anything like this before.

Some say Must be returned to qc, some say Majesco Sales Inc.

Thanks
