Prices are on the rise for sealed collector booster boxes from The Brother’s War, but why now? And why so much? Well, it turns out there’s a lot about this set that’s different from how they make sets now, and that just might be why it’s worth so much. But will the price keep going up, or is this just more Magic finance speculation?

Price History

In just the last three months, prices for sealed collector booster boxes of The Brother’s War set have risen from about $480 USD to about $615 USD on average, however this doesn’t tell the whole story. While on average these are the prices, many of these booster boxes have been selling for upwards of $850 USD. But why are these collector booster boxes from The Brother’s War worth so much in the first place, and why are they increasing in price? 

Supply, Demand, And Serialization

First of all, this is a premium product so obviously it’s going to have a high price point as a baseline. However, this is still a bit of an anomaly for one big reason: serialized cards. Nowadays, we won’t even get a serialized card in every set, and the ones that do have a serialized card only have one. In The Brother’s War collector boosters, there are a whopping 63 different cards that can be serialized, each numbered 1 to 500, for a total of 31,500 individual serialized cards.

These are all retroframe artifacts from the bonus sheet, and among them are some stinkers and some staples. They range from Mox Amber at the most expensive, fetching about $2,500 USD, to Sigil of Valor on the low end, going for only $150 USD.

Really the biggest thing affecting these prices are simply supply and demand. There is a fixed supply of these products, and a fixed number of serialized cards. Obviously, being serialized means there is a finite fixed number of a given card, so it has a limited supply. Demand is the more fickle counterpart, in that it’s always changing to some degree, and it really depends on the card. Aetherflux Reservoir for example is another card worth an insane amount of money; about $1,200 USD, but that’s mostly because it’s a card in high demand in formats like Commander. If they were suddenly to print a card that was functionally the same or very similar to it, but it only cost 3 mana, then I doubt it would hold that price, despite limited supply.

That being said, supply will only ever go down, more quickly and measurably in this case thanks to all of the serialized cards, and in turn, the price will increase as the supply struggles to meet whatever amount of demand that does exist.

As for why it has seemingly begun to spike in price in recent months, there’s not a clear definitive answer. It could simply be a natural increase as we often see happens over time, or it could be a strategic speculation given what we know about how serialized cards tend to hold their value over time. It could be that this is one of the safer bets in terms of investing in sealed products, and thus the price is going up in accordance with that. The price is also heavily tied to the specific artifacts on the bonus sheet within. If for whatever reason Altar of Dementia for example were to spike in price, then so too would the box.

Wrap Up

If you’re lucky enough to be holding on to any sealed The Brother’s War collector booster boxes, then congratulations. I can’t imagine that it wouldn’t continue to go up in price given what we know about the set and the trends we’ve seen so far. If you decide to open one however, don’t be surprised if you don’t get your money’s worth. While there is a lot of potential upside if you do happen to open a serialized card, the chances are that you won’t. That being said, if you want to open it just because you love opening packs, then go right ahead. Afterall, that’s what this game is all about.
