I want to know the answer to the following question:
What was the only coin with any silver content in circulation from 1965 to 1970?
All the background I'm provided with is that "In addition, an experimental $4.00 (Stella) coin was also minted in 1879, but never placed into circulation, and is properly considered to be a pattern rather than an actual coin denomination.". Is that enough to answer the question?
Answer: no
