CoinWatcher,
You just had a post yesterday reflecting your inexperience with a perf gauge. Nothing wrong with that, everyone had to learn at some point. But please understand that you have more to learn and one of those things is that you shouldn't be throwing this stuff on
ebay with those kinds of descriptions and asking prices. It is misleading, even if you offer to accept returns.
Think about it, someone bites on your misleading listing and sends you the $250. You pocket the cash and send them the stamp. They either measure the stamp properly or even worse, spend money on getting an ID/cert. You then have to deal with an irate customer who demands their money back. You incur shipping costs, have to refund their cash, and hope it doesn't get around that no one should buy anything from you.
Is this really worth the chance that you might score a $250 windfall if you can find a clueless buyer? And what does this do for the hobby? You now have a person walking around with a $1 stamp who paid you $250.
Another thing to learn is that not every rare stamp has made it way into your hands. You need to start always assuming the opposite. Assume that the chances you have stumbled upon a rarity is near zero. Assume that you have measured wrong, looked it up incorrectly, or that it has been altered or faked. Certainly don't throw it away, simply do what have been doing. Come in here and get these folks opinions on it. But listen to them, if they say it is not rare then believe them.
If you are bound and determined that these folks are wrong, then invest YOUR dollars in a good ID or cert. After you get it back, come back and let us know how it turns out. But don't throw it on
ebay with silly descriptions and big asking prices.
You are trashing your reputation, risking dollars and angry customers, and certainly not helping philately with how you are doing things now. Again, we all came through a learning curve. You still have time to write this off as 'learning how to list' and recover your reputation but if you do not stop it may become too late.
Respectfully,
Don
