Not sure about the Soriano, but the others that were shown above (Clemens and McCovey) most certainly look real! Why would I differentiate? Look at the top layer corners of card that cover the patch (in the "5" of McCovey and the corner of the "P" of Clemens). Someone is EXTREMELY talented to not only remove something without bending those areas - but removing AND replacing with thicker patches? I can see how it would be easier with squares, circles, or othe rpolygons that didn't hav ethe angles going internal - but those two inparticular would make me a believer that patchs can come in cards #'d to 50 and higher.
Not saying Soriano is real, but I definitely see enough evidence to say it is not an automatic fake.

Wouldn't it be easier for a person replacing GU pieces with patches to just go into the card from the side and not the front? Like DarkBrown mentioned it's the thickness of the cards that make it easier to mess with.
