>>20422356>I only learned about my grandma's stash when we were cleaning her flat after funeral. She had around 5kg of polish commie junk silver coins and none of her children knew about it.You have some cool stories and clearly know your stuff, you mentioned being a numismatist before so in addition to stacking weight I assume you have been collecting coins for years and have a respectable collection? I don't remember seeing you post anything from it though, do you have any pictures you're willing to share?
>commie junk silverI had a quick look on Numista and was surprised to see these silver coins they say were circulating commemoratives. If it's true that they were actually used in commerce in the late 1980s it's a remarkably late/young outlier for silver being used officially as money. The latest instance I know of are the bimetallic Mexican .925 silver center 10, 20 and 50 pesos from 1992-1995. What is your understanding of the relatively young Polish silver coins made from the 60s-80s, which ones actually circulated?
