Knowledge is power in the coin collecting hobby. The person who knows their stuff will be able to make a greater profit when compared to someone who does little research. There's stories of people who know their die varieties and will go to a coin show and buy a worn large cent for $20 from one dealer because they know its a rare variety, identify it as that variety and then sell it to another dealer by telling them its a rare variety and make 10x the money within the span of a couple minutes.
Heck, we exploit this disconnect between a true identified value and the value that someone thinks something is every day in our hobby. There are people that think a 1964 Kennedy is worth 50 cents and so they spend it at a bank, when in reality we know that its worth $9 or so in scrap silver, of course if someone really knows their stuff they might be able to know that its a rare die variety that can sell for $90 and they'll buy it from someone for $9 and sell it to someone else for $90.
You learned a lesson: don't sell things unless you know the true value of them. The person with a good eye and who is well-read on coins will always come out ahead.
If you don't want something like this to happen again, buy a few books or read online about various die varieties and check your coins over before you sell them.
YES!!!
