Hello everyone! I have this strange coin or medal of sorts that seems to be a copy of a Hadrian sestertrius (maybe something like this N#255785 . The coin is way too light at only 4,56 grams compared to 25 grams on a real one. the diameter is only 25 mm compared to 32 mm. the thickness is strange at 2,5 mm at the face and 1 mm on the flat part. I’m not as interested in finding the exact type as i am interested in getting to know how old it actually is, so please if you have any info about this coin/medal share it here. Thanks in advance!
Edit: It might be a copy of a dupondius too, the weight is still too light though.
