According to the IRS "If you sold an item you owned for personal use, such as a car, refrigerator, furniture, stereo, jewelry, or silverware, your gain is taxable as a capital gain. Report it as explained in the Instructions for Schedule D (Form 1040). You can't deduct a loss.
However, if you sold an item you held for investment, such as gold or silver bullion, coins, or gems, any gain is taxable as a capital gain and any loss is deductible as a capital loss." https://www.irs.gov/publications/p525
