Couple issues with this suggestion as it stands. First is the screenshot, as the $825 shown is just a balance with no proof of a transaction. For all we know you could have already had that money and just screenshotted it. Can you get a screenshot of the transaction? Make sure to blur out all personal info such as emails in the screenshot.

The second issue is the key value used. Even if both parties agreed to value keys at 1.65, it doesn't have any impact on the suggestion. We need to take key prices at the time of the sale. I found a few successful key sales around the time of the sale below, some of the screenshots are from older versions of forums posts mods have access to.

Using 1.525, this sale comes out to ~540 keys. However, if you had this listed for sale at lower than 540 (maybe 500?) before selling this will need to be capped at your buyout
