Delete duplicates based on date (google sheets)

Essentially,

Column G is a objectColumn V was the date that the object was sold on

Sometimes the object was sold numerous times, so lets say object X was sold in 2003, 2010 and 2013.

I want to delete the rows that have the sale in 2003 and 2010, and retain the 2013 sale.

What's the best way to do this? I have about 4000 rows so doing this manually would be a pain.
