Royal Worcester Vitreous Soup Plate

I found this "Royal Worcester Vitrious" Plate which seems to be from the 1880s.

Some of the details are:

There is a O or oval under the mark. Above the mark are the words Royal Worcester Vitreous. Under the O or oval it says "RaNo.68547".
The whole Mark is Blue.
There is also a very small (reddish) mark "W2297" away from the blue mark and another blue mark which I can't identify.

I would consider the plate to be in a pretty good condition considering it's possible age, but also I am new to collecting antiques things.

Can somebody help me with some infos?

 

W2297 is Worcester's pattern number. Replacements has a listing for it, but in a different colorway. Unfortunately they don't say when it was active or discontinued.

And to be more specific on the registry number, this one falls into the range used in 1887, so it can't be older than that. Remember that this is the date of registration for the design, not necessarily the date of manufacture.

 

Rd mark, rather than Ra. The reddish and blue marks are probably for the decorator. That O is a date code for 1889.

 

Do you think this plate has any value besides that I like it for what it looks like?

 

It's decorative, and people like blue and white. Here - London - about maybe 15 to 20 dollars?
