Offer arrived, can I still ask for more? after 18 years as a project coordinator

It is the first offer in 10 months and I do not want to mess it up. I worked as a project coordinator before this. I have a competing interview next week. Did you negotiate?

If they say no, consider asking for something else, such as a review in six months.

Ask about the range, not a number on its own. It felt more collaborative.
