Victorian or Edwardian commemorative vase

This vase may be from Queen Victoria's Diamond Jubilee (according to family lore) or it may be Edwardian (according to caption with photo of identical one I found in Google search).

It is similar to pieces of Queen Elizabeth II coronation memorabilia I found on eBay.

It has Canadian symbols, but British flags.

My mother informed me it was rare and valuable at one time. I received it in this condition - worn rim and feet. One foot is chipped and another appears repaired. Ink marks inside suggest someone used it to hold pens.
