Vessel with Lizard - numbers on bottom

This one I do love -- a lot. It is a very smooth vessel with a lizard on the top. I bought it in Canada about 3 hours north of Toronto at a Goodwill. I love the look of it and the smoothness of the clay. I realize I am a real sucker for super smooth clay. The lizard is quite well made, it seems to me. I have been totally intrigued by the numbers incised into the bottom and have had fantasies that it was an ancient piece that was somehow once owned by a serious collector who numbered his pieces blah blah blah. I had a friend who is an art appraiser look at it. She doesn't specialize in pottery but didn't think it looked too old. We haven't spoken since. (Just kidding).
Any thoughts?
Also, I am really wrestling poorly with these categories -- apologies.
