I have some old Indian coins and notes..I got a deal for 18 lakhs from a coin group..they told to pay 5500 for shipping charges, then later they pay half amount and another half amount after collecting coins from me..they told that they take insurance risk cover.. And they will sell these coins to their buyers in Malaysia.. I wanted to ask is, I am a middle class person..if I get that much of amount to my bank account.. Is it legal to get that much of amount..or am I taking any risk..and one more thing they told that they will give me receipt also..so if they give me receipt, can I pay tax for the amount I am selling.. Plz help me in this..
