That '49 looks great!
Too bad about the '39. I take you tried acetone....? At this point, you're not cleaning but conserving the coin, in my opinion. But I'm new to this so I hope you get some good advice from some experts.
The only thing that I think might be safe is to soak it in distilled water -- for months, and see what happens. But again, I hope you hear from an expert.
