Context is always important; labelling is rarely important.
You only use "only" with the cents value if the total amount is less than one dollar.
If you were writing a check for $0.65, you would write it as "Only 65 cents."
(In real life this happens very rarely. If you are writing a check at the grocery store for 65 cents something is very wrong with your finances.)
In the days when I wrote cheques, I'd write "One hundred and twenty pounds only' (for example) to indicate that there were no pence.
Context is always important; labelling is rarely important.
I was taught to write "and no cents" in that situation.
I see no reason at all to write only on a cheque.

I learned something new today. (The "only" bit.)
I'm also not sure if there's any place that would take personal checks in that amount. I'm sure there's a threshhold over which they want a bank check.
I'm not a teacher, but I write for a living. Please don't ask me about 2nd conditionals, but I'm a safe bet for what reads well in (American) English.
