I have no clue... nada, zip, zero that the gold bordered cards have value. I've been tossing them in the trash for years thinking there is no value (don't wory, I do not remember throwing away a Gaea's Cradle, heh), since they're not tournament legal- that's the tricky wording there: not tournament legal!!!! Yup, they are not considered "proxies" (in theory), but a strange Twilight Zone gray area. guess it depends on your playgroup.
Who has two thumbs and feels like a Thanksgiving turkey? Yup, this guy... The article for this Friday's Weekly Winners on mtgdstocks talks about the gold border cards and their value. Did anyone know a gold bordered Gaea's Cradle is worth $59.09?!?!?! Hell, the basic forests have a sticker of $4... that's probably worth more than 80% of the known printed rares in Magic's history. This is all strange, scary news to me.
My questions are these:
1) Where does one find legit prices then for gold bordered cards?
2) How would one go about selling/finding a buyer for said gold bordered cards?
.... [Haven't checked... Ebay?]
3) Opinion time: Is this just a phase? Are these prices sustainable? Or is there a cold chance in hell that some of the prices will increase?
4) Will the printing of this in this highly read website jump the prices even more or add value to the ones that were already cheap? (I mean, now a lot of folks are going to be digging around, searching their binders and boxes, for the gold border and either trying to trade them away or sell them, I bet...)
So these are all good questions and you should definitely feel good for asking them. Let me attempt to give some answers, although I don't speak from a position of any authority on gold borders.
1) TCGp has prices for the cards that are actually selling. I feel like that's an important distinction - if the cards aren't selling, it doesn't matter what price you put because nobody will buy them.
2) This is the tricky one. The market is "people who want to play the card in EDH/casual, and want a 'real' card but don't want to shell out for the black-border version". I don't think that you're going to get any collectors biting at this - collectors will buy a whole set, or maybe even just one deck, but piecing together a 75 card-by-card? Too much time. So, circling back, eBay is probably your best bet. Post your stuff for 5-10% less than the best current price, and it should eventually sell. I say eventually because these are not too rare, while the people who want one are.
3) It's not a phase, and prices will increase. But only some of them. These are basically extra reserve list cards, so stuff like Cradle is solid - it's not going to get a reprint that will tank the price of the original, thus putting it within reach of more people and reducing GB demand. Look at that Forest that they disingenuously cite as the "true weekly winner". I don't know where Stocks gets their pricing (median listing?), but that's CLEARLY a case of "someone listed some at a lower price and then pulled them", causing the arbitrary line to dip. It's not actually selling at $4. Same with the Randy B bio card. As to why they'd do that - well, it got your attention, didn't it?
4) Thanks, but our numbers are actually up lately. Moving on, no, making people aware of GB cards isn't really going to cause any market swings. It may convince one or two more people to buy GB rather than have a ripped index card saying "Cradle" on it, but there really aren't that many GB cards rotting in binders.
TL;DR - Cradle, Rector, V Stronghold, Survival, Replenish, G Monolith, maybe Yawg Will, and very maybe City are the GB cards that I'd say have legs. The rest are oddities that are mostly overpriced due to zero availability, but there's also zero demand.
These have had value for awhile now. The first time I became away of them is back when Wasteland originally spiked up to around $100, as the Gold boarder versions were going for like $20 or so. Most of what that holds value now are the expensive RL cards, like Cradle or Grim Monolith. I generally get my pricing from eBay completed auctions, as most sites don't really track these, similarly how many don't track the CE and IE cards.
Some sites have pricing on these. ABU keeps quite a bit of them in stock and isn't terrible as far as pricing goes. Personally, I feel that Gold border cards are going to go up quite a bit soon. Mostly stuff like grim monolith and city of traitors. People are playing old ed r casual formats and spending $200 for a city of traitors for a casual format is a bit of a tough pill to swallow for many. These are pretty good replacement options.
