Chinese coins, probably fake

For the specialists of chinese coins :
these come from a bulk lot I bought recently, about 30 of them in it
my first idea was to put them with the rest of worthless coins and other scrap, but then I noticed a difference between 2 of them
looking closer, I was able to determine 12 different pieces
does anybody have any info about this ?




thanks !

I think you should get better photos, but,

These are all fake. Notice the dotted background of the coins. These were used as replicas in a display case showing the different emperors from K'ang-hsi to Hsuan-t'ung.

If you get better photos, I can look closer and see how "old" they are.

Definitely fake. Besides the dots, the different coins should have different diameters.
