Maybe he means the thing "used with" the Birthdriver is just apart inside of it. Not something completely different. Not like something you could sell as a toy.
Date offers to trade a red Core Medal for 500 Cell Medals.
The kendo girl has two desires which causes the 2 Yummies.
There are side effects from the dinosaur Core Medals, which can lead to death.
Giru creates a Yummy from Maki, the world is about the end and Eiji says he wants to rescue everyone and the dinosaur medals react to that.

All of them can "hold" on to medals, but Ankh is an exception, because he's just an Arm. Unlike the other Greeeds who have a whole body. Maybe, because Ankh is just an arm, he has two "voids" of which one can "hold" the medals, and the other is for regular consumption for eating popsicles. Ankh also has Shingo's body to do the regular eating of food.
Remember when Kazari had the Kamakiri medal, and when Uva had the Cheetah medal? Nothing happened to them because they didn't consume it. Think of it this way, Ankh is like putting the Core Medals under his sleeve (including his 2nd Taka Medal, and yes I know they are kinda naked, this is just a metaphor), and Gamel was like actually 'eating' the Core Medals. If everybody goes beserk after consuming tons of Core Medals, Kazari and Uva would be already beasts now.
