the price is hard to say! Look at the authenticity. Second, look at the product! The age can't be named! I'll teach you a simple way to tell the truth from the false. Soak it in dilute sulfuric acid for 1 minutes, take a small needle and stick it on the money. It's true if the needle can stand but not fall! Because the copper oxide and "patina" on counterfeit coins are not as hard as the real ones because of their age, the opposite texture of counterfeit coins is loose, if you use acupuncture. The real thing will stand, but the fake thing will not stand.

If it is not handed down from generation to generation, you may be a fake.
