The forging statement seems rather silly.
$20 -> $200 is still a pretty good mark up, plus in cheques or similar paper based money transfers it's normal to have the amount written out in words as well as in numerals.
The decimal point protects the right edge of the amount, while the dollar sign protects the left edge.
Similarly, when people write out a number in English on a check, they often write "Twenty dollars only", not just "Twenty dollars", in order to prevent other words from being added to the end, e.g. "Twenty dollars and a hundred". (There's a nursery rhyme that goes "four and twenty blackbirds", so writing the smaller number first is clearly not unheard of.)
(Except in Belgium and Switzerland and this-one-valley-in-Italy et cetera, where it is just "nonante-trois".)
Compared to that, "drei-und-neunzig" is still not bad.
