If you need the money for real life expenses then maybe sell... If you are just going to put it back in the hobby then I reckon hold unless you will use it on something you would value more than the card..... If to spend on wax.... easy answer.... Don't sell!!!!
it's a good difficult position to be in Will
if you bought it for $1 and the dude is offering $7 then keep it
but if the offer can pay bills or more rare PC cards then don't even hesitate. 7x returns don't come round every 5 years, if ever
like Andrew said if it were /10 or less the decision may be a little bit harder. but despite being rare at /42 your chances of picking it up again are high
If he is offering 7x what you paid for it. And you are only considering it..
What about asking for 10x what you paid for it. Would that make you feel a bit happier to let it go?
Take the Money. He's come after you, that means he's gonna offer a price you cannot get elsewhere. If you are going to try sell it, then you probably won't get the same amount......and numbered to 42 isn't that low, and the value of someone like Ceballos is not going to skyrocket, unlike someone like Jordan, Kobe, LeBron etc.
You should also consider how some of those particular sets have gone up themselves, compared to 5 years ago. As a lot more people are interested in them.
I don't flip cards if they belong in my PC as I will regret selling them later.
In general I do not sell many cards. If someone gives me a good offer and the card means nothing to me I would sell, however I don't really collect stuff I don't want so its a catch 22 for me haha.
I've accepted the offer of about 8x what I paid to include paypal fees and registered postage. Should help fund the Crusade gold parallel I'm chasing plus the credentials #/9 I mentioned before plus some coinage left over.
