Online sales at a loss

I sold a personal collection of items piecemeal online. I am not a business, just a regular person, I have a 1099 K showing income over $5000. However these items were all sold for less than I bought them, though I no longer have receipts since they were purchased over many years.  Is this still considered income I need to claim? Is there some way I can show that they were sold at much less than their original value?
