A hundredth ...

Could you please find the meaning of the following proverb 'A hundredth of the goldsmith to one stroke of the ironsmith'?

By Googling, I can't find anything resembling that. Logically, I'm not sure about the TH in hundredTH.
If it is meant to be: A hundred strokes of the goldsmith to one stroke of the ironsmith, then I think it would refer to the goldsmith working with soft gold in tiny taps of a miniature hammer while the ironsmith strikes a hard metal with mighty blows of a massive hammer.

As far as I know, "A hundred (or hundredth)..." isn't a proverb or any kind of traditional saying in English. ~rb
