Chinese 5.56 magazine 5 round question

I say Chinese since it looks just like a 30 round mag I have that is marked made in China that I assume is for the 84/84S model. Would these little 5 round magazines have been for the same model? It isn't marked but is a double stack 5.56 feedlip that holds 5 rounds. They worth anything? Not sure what it was originally intended for.

Thanks,
Alan
