Tax threshold

I want to get rid of my toy collection that I've collected over the years and I'm so confused about taxes.

I'm not a business, just looking to downsize clutter.

Obviously I have no receipts for these things and I'm not looking to make profit, just recoup some money while getting rid of stuff.

Is it even worth the hassle after eBay fees and possibly paying taxes? I just want to know the best way to proceed.
