Selling my lightly used iPod Touch 7th Gen 128 GB

Apple's retail price is 299.00, and it's 349.99 at Best Buy.

What is a reasonable price for me to charge someone for my lightly used iPod Touch 7th Gen (128 GB - Space Gray)?

Note: I am not including earbuds, lightning cable, or any original packaging.

BTW...my username refers to my OLD iPod Nano 3rd generation, which I still own!
