I was just doing some reading about batteries on wikipedia and I came across an article on silver oxide batteries: You must be logged in to see this link. They have a high energy to weight ratio and very low self-discharge.
Some button cells (watch, calculator batteries etc) are of this type and can be identified by model numbers beginning with "S" and a labeled voltage of 1.55V (see You must be logged in to see this link. for a desciption of the button cell codes). I am not sure what percentage of the weight would be silver but it sounds like there is a significant amount in there. I was thinking you could ask at one of those battery specialty stores if they have a container of old watch batteries you could look through.
However they only buy scrap from companies, not individuals.

also to recycle them it requires pounds upon pounds of the things to make them worth while. Most watch battery changing jewelers may only send them in for recycling once or twice in there lifetime. When a mason jar is full, it may yield a couple ounces. IF you run across them and want to see them recycled, best to just give them to someone who has half a jar full. Its similar to gold plated jewelry, you need an bunch to make it worth while
