Price

No reliable price

The lowest and median asking prices coincide. This can indicate a thin market; the feed does not report a listing count.

Versus the market

Not enough trading to say

Its listings are too thin to trust the price, so it is not compared with the market.

Beating the market, or just riding it?

Not enough trading to say

Its listings are too thin to trust the price, so it is not compared with the market.

Describes the last 2 months, not what happens next. Not investment advice.

Is this card interesting right now?

Scores 86, but do not trust it

The cheapest listing and the middle of the listings are the same price ($21.48). That can indicate a thin market, but the feed does not report a listing count. We treat this price and its score as unreliable; check the actual listings. The score is computed the same way as for every other card, and on this one the ingredients are being fed by a listing that does not represent a real market. Treat the ranking as unreliable until the listings look normal again.

Why is it interesting?

Not meaningful here

The lowest and median asking prices coincide. This can indicate a thin market; the feed does not report a listing count. The ingredients are read off those listings, so they describe one seller's price rather than the card.

Is it becoming more popular?

Not enough trading to say

The lowest and median asking prices coincide. This can indicate a thin market; the feed does not report a listing count. A trend measured from that figure would say nothing about how the card is doing against the market.

Is it expensive or cheap?

No reliable price - last recorded $17.90

The lowest and median asking prices coincide. This can indicate a thin market; the feed does not report a listing count. The last recorded figure is shown for reference only, so it is not ranked against the rest of its set. The listings and recent sales on TCGplayer are the place to judge what a copy costs.

What makes this card unusual?

A Promo from a recent set

Promo is a widely printed rarity - 4,015 tracked cards share it. This is the Holofoil printing, which is priced as a completely separate market from the other printings of the same artwork.

Could you actually buy or sell it?

Slowly - it rarely trades

The price changed in 17% of our checks over the past year across 365 observations. TCGplayer's market price only updates when a copy sells, so a low figure means the price shown may be stale and any trend reading is built on very few real sales.

How does the grading fee compare?

Cannot say - no reliable price

The lowest and median asking prices coincide. This can indicate a thin market; the feed does not report a listing count. The grading maths starts from what a raw copy is worth, so there is nothing to work it out from. We track raw ungraded prices only - no graded sales and no population data. We cannot assess this copy's condition or tell you what a PSA 10 is worth. Check condition and comparable graded sales before deciding whether grading would pay off.
