Marino inherits antique pottery from the estate of his grandmother on March 10, 2018. He immediately sells the pottery for $15,000 to a collector who had made the offer to the executor of the estate several weeks before. The estate valuation of the pottery is $13,000. Marino's grandmother paid $20,000 for the pottery during an October 2016 visit to a flea market, convinced it was a valuable investment ¾ that she was getting a "steal" and the pottery would substantially appreciate over time.
