<p>NMC block 19200 was the first block to have merged mining hashing on it, Though I don't know if a merged mining pool found this block.
In merged mining, your submitted shares are passed to bitcoin to check if it solves a block. Then it is passed to namecoin. Each are independent of one another. If you find a NMC block, it's just that! No BTC are generated!</p>
