How do I price these items for a garage sale?

I am moving overseas and selling almost all my stuff. I don’t expect to get a lt o money for small items, but I was wondering how I can price electronics and small appliances such as:
19” TV (retail $98)
Sanio DVD player (retail $50)
Sony boombox (retail $60)
Microwave (retail $60)
Recliner chair (retail $300)
Panasonic bread maker (retail $120)
Cuisinart immersion blender (retail $30)
All stuff is relatively new, well-functioning and very clean. And how do I price appliances which retail under $20 (such as waffle iron, minichoper, hand mixer, blender)?
I have never been to a garage sale and have no idea what people pay for what.
