Theres one now, a silver person! lol. Yeah, when Revere was operating in Boston, they did things the old fashioned way, no doubt. It wasnt until the industrial revolution in the 1850s or so that silver plate came along. Anothing thing, in England, there was a very powerful guild system (union system over here) and they prohibited the colonies from all kinds of stuff as they wanted to ship finished goods to the colonies, not raw materials. Foundries for instance were absolutely a big NO NO in the colonies, not only because of economic issues but political reasons as well, cannons were cast from brass and no telling where that could lead!
So how did Revere and other silversmiths in american colonies get around all this, they melted english & spanish silver coins for their silver which is why american silver objects are known as "coin silver".
