Tantalum Capacitors. Common types and look-a-likes

I show the differences between various types of tantalum capacitors scrappers may encounter in more 'modern' electronics, roughly from the late 70's to mid-1990's, in high-grade electronics. And I also show a few little capacitors with the same yellow epoxy resin/ceramic which are NOT tantalum caps, but could be worth saving for other metals... such as silver and palladium.
