"Victoria Queen" coin

Any guidance would be much appreciated. I identified it years ago as from British Ceylon, but after perusing the Numista guide, it appears I was wrong.  Thanks in advance.

Why do you think you were wrong?  It looks like Ceylon to me.  What does the other side look like?

Here's the reverse.  I didn't post it because I really can't make out any details.  

Additionally, it's 3.4 cm in diameter, so it isn't the 1/4 cent.

Judging from the size it looks to be a Ceylon 1 cent coin

Much appreciated y'all.  Now onto early 19th century Chinese cash coins, for the real headaches.

Nahh, plenty of people around here are experts on the Chinese cash, it's one of the most commonly asked ID requests. You might try having a trawl through the previous ID requests, you might find your coins.
