Yes, they are some of the most amazing collectibles in the hobby for me. Unfortunately, the gen 2 ones are more rare from what I’ve seen. And some gen 1 copies are indeed very unusually rare. Sometimes, like in the instance of Magnemite (by Kinebuchi), a seller pops up with an old case of hundreds, and it swamps the market. Others are just plain hard as hell to find. Even Japanese copies are not all that common, but def more available.
