I've had this polish coin below for a while, but it has an interesting error, which I cant't find information about anywhere.
I known and understand that this coin has numerous replicas, but I believe that is not the case here. My coin has the same material and diameter, in addition to the weight with very little difference that I think is normal, even more in emergencial wartime coins, (my coin has about 6.75 to 6.80 grams) (and the official coin on Numista's page for example has 6.98 grams; has another example on Numista in the Exonumia section with a replica with over 12 grams).
My question at this moment is not about the total veracity of its authenticity, but about the present error on this coin.
Look at the reverse of it, below, at the word “IN” in the legend that has an inverterd. I found a interesting error and I would like to know if any of you have come across something like this.
Thank you all!!!
