I haven't drilled out many pins but this Germania warranted Oxford is the first one to make it a little more interesting 
Is this a common occurrence?

Magnetic?

Some old blades were made to be magnetic, as some sort of quack sales gimmick. Pins are usually brass, so I don't know how they would be.

I agree, that's why I was surprised about it.
I'm using a ball tip diamond bit. These pins were different than the others I've done.
They were a little easier to grind, and at the beginning I kept stopping, thinking I was getting into the scale because the tip kept getting covered with a black dusty buildup.
As I got deeper into the pins the crystal looking bushes started growing up around the bit
.
Finally got them out after about 4 hrs, I was doing my best to not screw the scales up I think they're going to look pretty sweet, I'm guessing they're bone.
I meant to keep the pins and look closer but wound up slinging them here and there.

at 1st glance, I thought I was looking at a colorized photo from the battle of the marne.I haven't drilled out many pins but this Germania warranted Oxford is the first one to make it a little more interesting

Yeah, kinda shows a micro view of how interconnected our world is
Simple, steel pin.
Brass, bronze, nickel silver are 3 common brasses [losely applied] all alloys of Copper with Zinc Tin and Nickel respectively. None of which is magnetic.
All will shed goldish-yellow grindings, nickel silver being the brightest.

Thanks Wombat. I've seen what you're saying recently since getting into a little jewelry repair and cleaning up some brass rings of my wife's and using a magnet to help identify if they're brass plated or all brass.
The structure of the drilled pin reminded me of how metal shavings look when being affected by a magnet even though in this case they were only slightly attaching themselves to the tip of the bit and was the first time I've experienced it while removing pins.
