Old Parr 15 years old

[JMC]

I bought a Old Parr 15 years old.
It´s a dark blue ceramic bottle.It was made to celebrate the 500 years born of Thomas Parr.

In the fund it has recorded "Royal Victoria Pottery".
Someone can tell me more information about this release,particularly:
In what year was release?
How many was made?
What is the value of it?

Thanks
