You might be confusing shares with blocks.   Where are you mining?  Pool or solo?

The miner software computes hashes at a lower difficulty than required for a block.  This is probably what your seeing.  If you were pool mining, these would be shares.  These lower difficulty shares could be a solution to the higher difficulty required for a block.

If you do solve a block,  You will see 50 BTC in your local Bitcoin client.

Nice.

With how long it takes to mine, the cost of electricity... Bitcoins should far exceed real currency in value. I can easily work a minimum wage job for less hours and make 50$.. But to make 50 bitcoins?! Jesus Christ...

No, solo mining does not have that concept at all. There's one difficulty and one difficulty only - the one that matters to make it into the block chain.

pyrohydrosmok, mined blocks do not show up in your wallet until they are buried under 100 other blocks. That's to prevent them being spent in case the block chain splits, and your block ends up NOT being the one chosen by the network for the chain. Give it another 13 hours or so, and then it should appear in your wallet.

I didn't know you were actually calculating the hashes manually.  Most people just hook up a computer and let it run.
