Uhhhhh ..... how much tax was paid on these sold items? Wouldn't this be considered taxable under either income or capital gain?

If you actually are operating as a business rather than a hobby, then yes, both State sales and State and Federal income taxes would be due...not really capital gains since it sounds like inventory rather true investment goods, but in the unlikely event one of them was above the first two tax brackets, it would be worth trying that if they'd held the asset over a year.
Fortunately for them, the IRS almost never screws with such small fish...though some State Departments of Revenue are a lot more desperate and will pursue very minimal cases for their 'Object lesson' value.
