Wording for monetary gifts

Just don't register, people will take the hint and give you money. There's no need to ask.

There is no polite way to ask for gifts of any sort, much less money. Miss Manners recently suggested that guests consider not gifting at all couples who are trying to be creative in getting money out of their guests' wallets.

It is incredibly impolite and tasteless to ask for money. You do not mention gifts of any kind on an invitation.

Exactly this!

There is no proper way to word that, as it's rude to ask for money. And definitely do not put anything about gifts or money on your invitations. In my experience, people know to gift money for a wedding. We received 100% cash gifts from our guests, no physical gifts for the wedding. You don't need to tell adults that, and again, it's very crass to do so.

I registered for my showers and got all but 5 gifts, so I assume now the only option for the wedding will be cash, 1 of the 5 gifts or nothing. I would recommend having a small registry especially if you have a shower. There are some people who just want to give a physical gift and if you give them no option who knows what you will get. We mostly did upgrades.

Don't register. Everyone almost everyone will give you cash or check, Don't ask. They'll get the hint. It's sort of the norm in my family to just gift a check.
