I need help evaluating this coin please.

Welcome to Numista!

I think it's a very common coin, so eBay is probably the best place to do your research (be sure to only search on sold items).

Have seen many videos and blogs about these coins and they are apparently worth a huge amount of money but  sceptical as the internet can be so misleading. 

These is just a standard circulation coin from Singapore, worth only a couple cents

N#1671

Over 40 million struck, approx £0.20 value.

More in the U.S.

eBay buyers paid on average $3.50 including shipping, to obtain this coin (4 sales, all close in price).  

This coin is probably sought by collectors of coins with sea creatures.
