Silver has anti-microbial properties, so it's not completely silly to make bandages with a small amount of silver dust in them. Considering that this package cost only a dollar, there's surely not very much silver in there, which is probably a good thing as too much can be toxic.
Personally, I'll stick with Neosporin.
