anything silver is good! however, sterling silver jewelry aren't backed by government so it is harder to convince buyer that it is genuine 92.5% silver. Also, there are a lot of scammer who stamps 925 or sterling however they don't contain 92.5% silver. They are selling 50% - 65% Silver Items or German Silver/ Paktong Silver MARKED as 925 Silver!!! So that being said, junk silver coins are much more reliable for you to accumulate real silver. IMO
