"Good" news -- these are replica Cup 1s, not real ones, and therefore no great loss to write off as damaged.
Real Cup 1s will have a Porsche Part number cast into them:
I had read years ago that the chroming process weakens the wheel and something that Porsche and Mercedes did not recommend. I also remember it being a huge fad in CA during the 90’s and often done by dealers or after purchase but rarely if ever done from the manufacturer. I would be surprised if the chrome wheels were on the original build sheet for this car.

According to Adrian Streather book they were not available in 91. So likely aftermarket.
In fairness to the mechanic they did suggest to check them out before confirming what they were.
Looking for wheels, came across a set of boxster twists that I understand will for the 964 and the tires I already purchased. Seller wants $600 and they are not perfect. Is this reasonable?
Alternatively I could buy something new. This seems like a good look and OEM wheels so I kind of like the boxster option.
1. Now that you know they are defective, you cant in good conscience drive them at more than a limp home speed or allow another to do so. They are not roadworthy, period.
2. Chroming aluminum is prohibited on aviation products. Cant remember the details of why it damages the metal but its been fairly common knowledge amongst this necessarily conservative bunch for some time.
3. The bolt pattern for your car is common to so many Porsches and there are so many used sets available from many sources, Id think there's no reason to purchase anything with any damage. I personally would trust OEM wheels for cornering strength, high rotational speed strength, and proper look for your car, whereas an aftermarket brand would require research to determine suitability in these realms. You might consider this an opportunity to go 8" fronts and 9" rears if you do decide to purchase another set of tires.
Good luck.
For $600 I think the Boxster wheels are an acceptable option. They'll be safer and allow you to enjoy the car until you find a set of wheels you really love.
So I found some replacement wheels. They are coming from a fellow Porsche enthusiast and were stock '99 Boxster wheels. They have a few scrapes, so I think I can get some paint and fix them up prior to mounting the tires... Any special handling involved in painting wheels?
