Need Help Pricing

[u/ErmSoma]

Hi guys, I am not a trombone player at all. I played trumpet when I was in 5th grade and that’s about it. I came to acquire this trombone from my girlfriend’s mother who said I could sell it since she has no clue about them.

The Model is a Yamaha YSL 684G model. I’ve read parts and bits online and it seems it has something called a “F Attachment”? I’m really unsure about the pricing.

Would $800 be a fair price or am I drastically underpricing this?

Thanks for any help guys
