i have never seen it personally but have read numerous stories of them lowballing a widow over guns and many other types of items!Yeah, but that's how estate liquidators find business. Most of them have a gun guy on speed dial but if you have a relationship with one, they can be a source.
Estate sales, not so much. Typically the guns will be sold before the public sale happens.
As an aside, not always but all too often, they go to the liquidators cousin for a too-low price. Cousin then hands them back to the liquidator for a small fee and the liquidator can take their time maximizing return while cutting the widow out of any profit.
Sad but I've seen it.
