The 6Billion was previously bought in the garage for 10k, before then being retired and becoming limited.
Supply is widely distributed — no single holder owns enough to register as a hoarder.
As 6Billion is extremely hard to spot in trading, with a MU of just ~89, which is lower than the majority of rare items, its incredibly difficult to get one for only 250K. This can very often be used as a 500K add in trades, or be exchanged for other 500K items such as Beachball, Shooting Star or Overdrive.
