I’m unclear if you were asking this tongue-in-cheek, or if you really were interested and simply used an arbitrary asset for your example, but in case it was the later, here’s my understanding: Do you account typically report FIFO or LIFO? You can register a capital loss of $100 if you account last-in-first-out, but will be on the hook when you sell your $10 gravel on the future at any price higher than $10. You’d register a capital gain of $90 over cost if you account first-in-first-out. AFAIK, in either case you have to account for all of your transactions the same way, for the year in question. It’s not pick and chose to gain the best benefit. Tax rate in either case would be calculated based on how long you held your gravel.
