Liar Bank Jar

I was shopping for my nephews for christmas and saw this Zillionz Girl bank.
The jar is no bigger than a large Jiff peanut butter jar, its pretty small. Tell me.. how the fuck does 149.73$ worth of change fit in a jar that small? I also saw a larger version, around the size of a 2 liter of pepsi.
The large one seems more reasonable with only 14.38$ in it. Jar of Lies
