How can you tell if a coin is premined?

Even if the first blocks don't have an unusually large reward, you can check how many blocks are already mined when a coin is released. Type 'getinfo' in the debug console of the wallet-software. Or, if a block explorer exists for the coin, you can check how many blocks are timestamped before the official release time.

Some premines consist of the developer mining a few thousand regular sized blocks before releasing the software to the public.

See here example of COINO

https://bitcointalksearch.org/topic/m.4672267

"1. First block: size 2200000 coins
2. 140 blocks: size 1 coin
3. 2794284 blocks: size 36 coin
Then block size is 0 forever

Here nSubsidy part of code in main.cpp:

int64 static GetBlockValue(int nHeight, int64 nFees)
{
   int64 nSubsidy = 0;

   if (nHeight < 2794284)
   nSubsidy = 35 * COIN;

   if (nHeight < 140)
   nSubsidy = 1 * COIN;

   if (nHeight == 1)
   nSubsidy = 2200000 * COIN;

   return nSubsidy + nFees;
}"

Is it possible to see if an altcoin has premined and the amount of premine that occurred?
