"Breathing" on a coin

Sequitur

Recently, had to return a proof coin to the Mint because it was scratched. Today, I received the $10 2003 gold commemorative from the Mint, and it too appeared to have a scratch on the reverse.

I don't normally pop open cases, but I was so damn pissed at the prospect of back-to-back Mint returns that I opened the holder and blew on the coin -- turns out it wasn't scratched, but instead was an odd-looking fiber that held fast on the coin until I dislodged it.

Now I regret having opened the container and regret breathing on the coin, esp. since I've seen some warnings about this. (And then I dropped the gold piece on the kitchen floor, too, but I had already returned it to the plastic holder and it looks none the worse for wear. Damn coin is as troublesome as the Wright Bros. first plane.)

Any long-term consequences from blowing or breathing on gold coins in general, or gold proofs in particular? Or nothing to worry about?

At this point, I think I would leave it alone and hope for the best. At worst, you could always dip it if a problem shows up. If you don't dip it too long, no one will ever know.

Shhhhhh! Don't let anyone know I told you this.

I try to stick to coins that take my breath away...

Be sure to stop in at the DARKSIDE FORUM ( World & Ancient Coins Forum) where many of us actually touch our coins without wearing lint-free cotton gloves.

I beg your pardon!

The main worry is water droplets. it's harder than you think to blow w/o any droplets of moisture coming out. If you didn't see any spots you're probably ok.

Given the fact that it's a gold coin (as opposed to copper of silver), I wouldn't worry about it too much.
