Was wondering if someone would take the time to identify these coins for me, date and year if possible? Also I have spent a lot of time googling about these types of coins still don't get it! I showed it to someone who knows a little bit about some of these coins but said he wasn't sure, so now I'm asking the expert(s). My friend thought that one of them might be a Kangxi coin but not certain. So I posted pictures for you which are numbered, so starts with Coin 1 and Coin 2 which would be the front and back of the coin, so Coin 2 and 3 are the front and back of another coin and so on and so on. Hope this makes sense. Also are some of these coins silver? Anyone know what the weight would be if it were silver? Asking a lot but would really love to know about these coins, where are they from, date & year. Thank you very much for your time.
