I'm assuming those are Zimbabwean dollars.
(A little note (sic!) on the Zimbabwe dollar and hyperinflation follows....from Wiki)
On 12 January 2009, Zimbabwe introduced the $50,000,000,000 note.

On January 16, 2009, Zimbabwe announced plans for imminent issue of banknotes of $10 trillion, $20 trillion, $50 trillion,
and $100 trillion. At the time of the announcement, the last was valued at around 30 US dollars, but that value was expected to evaporate swiftly.
[41] Notably, those plans open a gap in the banknote series: there are none on the order of $200 billion or $1 trillion. It would take 100 of the $100 billion notes to make the same value as the next larger note, $10 trillion.
On January 29, in an effort to counteract his country's runaway inflation, acting Finance Minister
Patrick Chinamasa announced that Zimbabweans will be permitted to use other, more stable currencies (e.g. the
South African rand) to do business, alongside the Zimbabwe dollar.
[42] Although only licensed companies are allowed to accept foreign currencies, this has now become a common practice. In fact, according to local residents, even street vendors are already refusing to accept Zimbabwean dollars.

In February the government of Zimbabwe revalued its currency. One of these new Zimbabwean dollars is worth one trillion of the previous.
[44] This move took the number of decimal places removed during the period of hyperinflation to 25 (1025 = 10 septillion
short scale; thus, if no revaluations had taken place, Zimbabwe would now be issuing 10 septillion dollar notes).
In March, 2009, an independent newspaper published by exiled Zimbabwean journalists known as
The Zimbabwean launched
The Trillion Dollar Campaign, a marketing effort in Johannesburg, South Africa, to protest a hefty import duty levied upon it by the ZANU-PF government. Zimbabwean banknotes of enormous monetary denominations were distributed freely to motorists and pedestrians. The worthless notes were even used to plaster walls and billboards- all printed with slogans such as 'it's cheaper to print this on money' and 'fight the regime that has crippled a country'.
