Sounds like it might just be a high grade circulation strike, photos would assist.
There is no proof strike, but there is a specimen strike (McD lists specimens under the proof column to save space). The specimen strike has semi-lustrous, semi-matte fields (usually dulled due to toning), similar to the other Heaton mint specimen strikes.
You can see an illustration of the specimen strike here:
