These do not represent silver at all, but rather are shares in silver mining companies. Companies rarely mine silver alone, as normally silver is found within, or alongside, ore containing other metals, such as tin, lead, zinc or copper. Therefore shares are also a base metal investment, rather than solely a silver investment.  As with all mining shares, there are many other factors to take into account when evaluating the share price, other than simply the commodity price. Instead of personally selecting individual companies, some investors prefer spreading their risk by investing in precious metal mining mutual funds.
