From my experiences, games that are accurately priced don't generate very much discussion about the price. However, games that are way overpriced will have more posts about the price. And people will nitpick which then makes the seller annoyed. But if you want to ask top dollar, your game better be in pristine, mint condition without any flaws.
Take this BSD for sale thread for example: https://pinside.com/pinball/forum/topic/for-sale-bram-stokers-dracula-3. Many people comment about it being a nice game at a nice price. Not very much drama.
This for sale thread on the other hand...https://pinside.com/pinball/forum/topic/for-sale-family-guy-stern-2007-2017. He was way overpriced on his game (it was originally $8,499, but he's since lowered it) and the users let him know about it.
If you're going to open your ad up for discussion, you better be ready for what the people in general think about it.
