It's a lot more than you might think, and I couldn't find a comprehensive list of the non-spacecraft objects, some of which are hinted at in the first paragraph.
The later Apollo missions (13-17) deliberately crashed their 3rd stages into the moon, in part to provide a signal for the seismometer packages left at each of the landing sites. They hit the moon a little faster than the Falcon 9 2nd stage will hit (2.6km/s vs 2.43km/s for the new one).
All of those impact sites have been located but the last one wasn't pinpointed until 2016: https://www.cbsnews.com/news/moon-mystery-solved-apollo-rock...
