Ancient Chinese Coins, What Are They?

It's pushing 8 hours... how long is long?

Edit: thanks for the chart, bobbyhelmet. I'm seeing similarities on 6 & 7




I'm not a good tracker on this species so I didn't really look them up at all, Enjoy the hunt and Good Luck

I'd just give them a rinse to remove loose crud, then leave them be. If you can't see a character then give it a quick rub with a fiberglass pencil to remove the grit in that area.

I'm working through some Chinese cash myself right now. Here's a string of 250 I have to catalog and pluck out doubles from:

I've been getting back into Chinese cash, made the switch to Hartill from Schjoth so I have to go through all my books and redo all the tags as well. I have that string and a few bags with maybe 200 more to get through.
That string has some awesome stuff in there:
-About 10 Sendai (Japan) square cash
-Multiple Liao dynasty cash with readable legends
-Bunch of Ming cash as well.
Lots of doubles in there. I figure I can make back the cost of that one batch by selling only a few doubles.

I don't collect these but its cool seeing them strung like that.Only read about them being organized that way.

I have always thought coins with holes in the center were cool, and yeah it's really sweet seeing all of them on a string like that.

Think I read a news story once saying the vending machine industry didn't like the idea of holes in coins because they could catch up on the machinery. But I always thought if the inner hole is calibrated right, then the coin could be dropped onto a graduated spike and when it stopped if it wasn't the right diameter then it would be rejected, a double calibration test.



So I'm starting slow, I put one of the worst in distilled water yesterday at noon, ~34 hours ago. About an hour ago I tried to brush it and has little success, there was even an encrustation in the hole, I was able to get that out and it's back in to soak. If it's 1000 years old what is a few more day's, week's, month's...



That's a before picture I didn't take a during picture, but I'll have an after picture... in day's... week's... month's...

Been looking at the 'odd one out' again and I think its either Yuan De or Yuan Feng. Struggling to get pictures of either in good condition though to compare, maybe others can find some, my head hurts now

Thanks jcm, its been driving me mad

Ok, it's H 16.233, small tong. He rates it at R9, on a 0-16 rarity scale with 0 being nearly unique and 16 being so common you can't walk around the corner without tripping on one. So yours is somewhere in the middle.
Yuan De (1119-1126, H 18.95)(W. Xia Dynasty, 1032-1227) has the Yuan å.ƒ in top position, De å¾· in bottom position. I have one floating around somewhere if you want to see a pic.
