In those days some families whole possessions weren't worth one single gold coin.
I have repeatedly stated that different types of precious metals where used, including silver and bronze. Which poor families could afford, often coins where also divided, this is where the term quarter comes from for example. Currency has been used by most people for the majority of our known history, it is as old as civilization itself.
Great so you admit you were wrong.
That took some time!

Gold and silver coins sometimes mixed with copper and other precious metals.
