Can you tell me about the 1890 Hong Kong five-cent coin?

1890 should be the period of Queen Victoria's reign, so the portrait should be of her. You can confirm it by looking at the word VICTORIA on the side of the head.

But within a few years it was Edward VII. The value of Hong Kong dollars during this period will vary greatly depending on the era. Since I don’t have Hong Kong dollars from this period, I checked the information and found that there are no rare ones in 1890.

I didn’t guess. If I'm wrong, this should be made of silver. It's over a hundred years old, so it's worth any amount.
