On the left my piggy bank with collection number 865. I marked it as Polish with a question mark. The right one is an image from an auction box (ebay.com – Saint Petersburg, Florida, USA) with Russian porcelain. So it may well be that my piggy bank is 865 Russian, but Polish is still a good option for me. Because the seller on eBay could also be wrong. The marks/stamps are still illegible.
