Meaning of 準備ができたものから


[Context](https://www3.nhk.or.jp/news/easy/k10011990471000/k10011990471000.html):

> １０円や５０円などほかの硬貨も、 **準備ができたものから** 作り始めます。  
>  They will also start making other coins such as the 10 and 50 yen _from the
> thing they were able to prepare_.

I can't even guess at what 準備ができたものから is meant to mean in this sentence. What
is もの referring to? The context doesn't help me at all.

Edit: Presumably it is simply "after they've made preparations", but I still
don't understand the ものから part well.




This から stands for the starting point of sequence, just like English _from_ in
"from the largest to smallest". [The
dictionary](https://dictionary.goo.ne.jp/jn/45491/meaning/m0u/) says:

> **５** 動作・作用の開始順序や発端を示す。「先着の人から入場してください」

So,

> 準備ができたものから  
>  _in the order they reach readiness_  
>  _(starting) from what has been made ready_
