Silver is in all electronics the problem is the concentration. In gold the plating is worth 50+ dollars a gram in silver its worth 1 dollar a gram. If you have silver in concentration than its worth the effort but plating is worth nothing. This is why contacts and solder are what is discussed. Solder verges on not being an option with the amount of chemicals and some of the other metals that are included with it. Some Al plated with Ag is profitable this is mostly found in HAM type radios. Some capacitors have silver some Ta cap and silver mica the look like brown dog bones. AgO batteries have silver they have a marking in the 3** series 301-399 its on the battery hearing aide, watch, medical device, camera flash just for some ideas on where to look
Silver plate on pins and flatware HVAC solder joints should be sold as #2 or they can sometimes be reclaimed in the refining process. If you have tonnage you might get paid for it at the refinery.
