You can refer these posts
here &
here to understand about these enigmatic religious Hindu tokens.
Many varieties exists with different metal compositions.
What is the metal of the token you are possessing ?
AFAIK these tokens with
silver &
gold compositions are equivalent to market value of gold/silver+ making charges , however in case of copper tokens normally in range of 1 - 2 USD/piece , as these are all contemporary tokens thus doesn't bear any numismatic value rather than religious sentiments.
