So since silver has antibacterial properties, does this mean that people got sick less from coin-borne germs back in the good old days?
No. And in the good old days, the public rejected Gold Coins because they had a recluse design and "germs" would get into the lower spots.
The numismatic term is incuse. HOWEVER, given how rare gold coins were, they may also have been recluses...
As it turns out, copper and its alloys are also anti-microbial. Most US coinage is either plated with pure copper, or an alloy of a very large amount of copper and a small amount of nickel (to give it color).

Paper money is very much a vector for disease but coins are pretty clean. Silver's antimicrobial properties make it less likely to carry germs but no coin is very likely anyway.
Auto-correct maybe? I really wish I could turn that off. I sometimes "coin" new words for effect, and auto-correct likes to argue with me.
