Stan, You are experiencing (most likely) a resonant vibration. I deduce that many Coupes have experienced it at one point or another. I am told it can cause structural failure.
You will probably get lots of explanations and advice on how to deal with it. Many will include an inspection or replacement of parts associated with the nose strut. I have tried most of them, I think. But, sometimes, just applying back-pressure on the yoke will mitigate the problem until the resonant frequency speed is transited. Sometimes forward pressure does the trick. Sometimes it takes one after the the other. Another trick is to slightly decrease the nose tire pressure. (I think that is because it makes irregularities in the tire less pronounced and cushions the otherwise sharp "bumps" caused by such irregularities.) I recently found that I had a flat spot on my nose tire that caused it. I changed out the tire and all was well.

I flew this landing with 17 to 18 lbs in the nose tire. As you can see I landed on the mains, set down on the nose, rolled 300 to 400 feet and then it almost felt like it was going to break off until I got to about 15mph.
