See here: https://jsfiddle.net/zgxenf0t/
Some cases of validation check:

$ 0.00 = false
$ 9.00 = true
$ 99.00 = true
$ 999.00 = true
$ 9,999.00 = false
$ 99,999.00 = false
$ 999,999.00 = true
$ 9,999,999.00 = false
$ 99,999,999.00 = false
$ 999,999,999.00 = true
$ 9,999,999,999.00 = false
$ 99,999,999,999.00 = false
$ 999,999,999,999.00 = true

$ 1.00 = true
$ 10.00 = true
$ 100.00 = true
$ 1,000.00 = false
$ 10,000.00 = false
$ 100,000.00 = true
$ 1,000,000.00 = false
$ 10,000,000.00 = false
$ 100,000,000.00 = true
...

Numeric alias is ok
