Swift moving metallic orb, traveling East to West.

I was watching out my north window watching the sun getting close to setting. The Orb, much like a Christmas tree ornament, was highly reflective reflecting the sky color and cloud texture. It moved very rapidly from right to left and was gone before I could turn my head to track it. The object size was that of a quarter dollar coin held between thumb and finger at arm's length.
Date is approximate.  PD
