Extracts from above:
This one is typically AE
Boonognog: One hundred one thousand seven hundred twenty-two and 00/100 -----
and this one BE
panjandrum: One hundred and one thousand seven hundred and twenty two pounds only.
Note that in AE "and" is not used between the thousands, tens and units. In AE the cents are written in numerals over a hundred, whereas in BE the "and" is used, and the pence doesn't get a mention if the value is zero.
If the amonut included pence it would be added as "...pounds and fifty-two pence only". The pence rule is sometimes ignored and people write "...pounds and 52p only". A few people will omit the "only".
Strictly speaking, all compound numbers between twenty-one and ninety-nine should be hyphenated when spelled out.
One hundred and one thousand seven hundred and twenty-two pounds only (assuming the currency is GBP).
