Is 大判小判 a word on its own?


While reading a short story I came across the following: 大判小判.

I understand that [大判]{おおばん} can refer to a large traditional Japanese coin
and [小判]{こばん} can refer to a smaller traditional Japanese coin. As there was
no particle placed between the two I was wondering if they had a special
meaning when written together like this?




In fairy tales, yes, we sometimes hear 大判小判 almost as a set phrase. 大判小判がざっくざく
is a famous [4-4-5 sound](https://japanese.stackexchange.com/q/30106/5010)
phrase found in a children's song called
[花咲かじいさん](http://www.worldfolksong.com/songbook/japan/doyo/hanasakajisan.htm).
I think this phrase is known to most Japanese native speakers.

I would say 大判小判 is preferred because it can sound nicer than 大判と小判 or 大判や小判
in some situations. It means nothing more than large and small traditional
coins.
