I tried to report the fake/counterfeit coins to eBay, but so far the business of these guys is going on well.
Words in fake coin listings : TOKEN-SILVER, TOKEN, token Silver Token
If any such words are there in silver coin listings from India, most likely those coins might be fake.
I can share the names of eBay sellers too who are involved in such business, But beware of buying coins
from these sellers.
