The person that invented the stamp Matrix type effect is Amando from the U.S.

The person performing the trick is most likely a magic dealer simply selling tricks at a magic convention in Italy.

This is a classic effect usually done with poker chips, coins, and playing cards. The name escapers me right now, but Albert Goshman performed it with playing cards and a folded sheet of news paper in his close-up show and is published in his book, and on his DVD.

I would say that stamp version is very magical and different then the original versions. Of course the original versions are published in books and can be done with no gimmicks.

Armando Lucero - I have a few private videos, with his show at different conferences. I saw a version with postage stamps on sale - a very long time ago - I can not remember the artist's name. Although the version in the video is probably not for sale.
Honestly, I can not understand whether it's agility or a trick? I don't know. But in the version I saw, used a trick.

I know the creator of the trick, he is from France and may be in his 80’s now

Claude Rix is his name!
