What price was on pre ico? 0.03$-0.05$?
ETH was around 50 usd in PRE-ICO. PRE-ICO investors got 606 SNM per ETH. SONM decided to give 4x that amount of tokens for PRE-ICO investors now due to increase of price of ETH. This means they paid 50 USD for 4x606=2424 tokens, thus snm token costed little over 2 cents of dollar for them (50/2424).
