I'd be surprised if those are mica caps, but they could be. If so, they are probably ok. I know Micamold made some caps that looked like mica but were actually paper.

I'm not the best person to ask about safety caps...I have to research them every time I need to use them to make sure I get the correct type. But here's how I try to remember: X safety caps go across the line, just as the lines of the X are across each other. Since C100 and C101 each go from one side of the line to ground, I think you need Y type caps. Hopefully someone smarter than me can weigh in here.
