I was informed through a notification that this post had mentioned me, in which 
In fact, its so rare, there are only 3 of these cards in existence:
What happened was this, and I remember it clearly.

Is it really the most expensive dCity NFT ever sold?
Of this I am actually not sure. At current SIM prices, its only about 240 HIVE, or ~185 dollars.
In HIVE terms it might not be the most expensive ever sold, as we have had some mania phases with dCity before, but in SIM terms I am relatively confident that this is the case.

But even this top card is unlikely to have topped 250k sim! Anyone can correct me if I am wrong, there is no good tool for me to search for most expensive cards ever sold. But I can search for the market history of 'APARTAMENT' card itself:
Here we can clearly see that my patience has paid off, and I think the future is bright for both dCity and its rarest NFT.
