A shiny dime sized metalic object appeared out of nowhere and vanished within 20 seconds overr San Francisco

I was on a tour boat on San Francisco Bay returning from Alcatraz Island. I was with two friends but they did not witness what I saw becuase by the time I told them it had already vanished.

The boat was apraoching San Franciso Pier 41, when I noticed a shiny metalic grey object that suddenly appeared over downtown San Francisco at no more than 10,000 feet, It was the only object that caught my eye, from my view it appeared to be just a bit smaller than a dime, it moved slowly upwards for about 10 seconds than it rotated about 45 degree as if making a sharp left turn.

The bottom appeared flat with a slight bulge and a white center. There was shiny reflection that lasted about 10 seconds then it changed to a diamond shape and sped updwards at incredible speed and vanished completely leaving no trace.

The sky was mostly clear except for patches of low fog over the bay.
