It's either gone up the last month, is going up by the next issue or is a mistake.
The online Beckett , seems to have an arrow stay around too long(after it's already gone up) OR the arrow pops up before the price goes up...
I use, (Check recent price movement) on Beckett, but it only works on the last 10 cards per player, I would love to see the History on a single player, that would be great.
A more important question would be, why does the Beckett even exist when only a small percentage of people use it for valuing cards??
Seems to me that feebay is the new authority on card prices as pretty much no one will pay anything over last feebay sale values unless they desperately want the card.
I think using both beckett AND feebay you can gauge a good price. Beckett is out of touch a lot with card prices, but yes, there are also a lot of BS sales on feebay.
