Hong Kong 5¢ 1971

I have a five cent Hong Kong coin from 1971 with no mint mark. Could this be added to the list please. 

Picture?

Forget it I found the H but it is so faint it is hardly visible. Bad strike.

Where to find the mint marks!

Or maybe just a well circulated coin?

No really good condition, just the H is barely visible. Everything else is clearly struck.

Could do with a high-quality image of the H mintmark to add to the page
