May be this is mining on some private pool. All supply now is 20k coins as it shown it Top100. This value is smaller than 8734 * 15 YIC. But where are the rest coins?

// miner's coin base reward
int64_t GetProofOfWorkReward(int64_t nFees, int nHeight)
{
    int64_t nSubsidy = 150 * COIN;

    if(pindexBest->nHeight > 5000)
    {
        nSubsidy = 15 * COIN;  
    }
