Beating the market, or just riding it?
Not enough trading to say
It trades too rarely, or has too little recent price history, for a 2-month comparison with the market to mean anything.
Describes the last 2 months, not what happens next. Not investment advice.
Is this card interesting right now?
Notable - 85 out of 100
It ranks above 86% of the cards we track. The score describes the conditions around the card today - how sellers are pricing it, how it is trending, how steadily it trades. Its weights were tuned on how cards moved over the following 60 days, so a high score is a tendency across many cards, not a forecast for this one - and it says nothing about whether you will enjoy owning the card.
Why is it interesting?
Climbing this month and climbing for 2 months
It has done better than the rest of the market over the past month. It has done better than the market over two months, which is long enough to be a trend rather than a blip. Working against it: median asking prices sit below the recent-sales market reference - sellers are pricing more aggressively.
Is it becoming more popular?
Yes - consistently
Compared with the Pokemon market as a whole, so a rising tide does not count as popularity. In this market these trends have tended to keep going rather than reverse.
Past month+16.5%
Past 2 months+35.0%
Past 4 months+53.6%
Is it expensive or cheap?
$14.62 - mid-priced for its set
At $14.62 it is mid-priced for its set - number 30 of 58 by price. It costs more than 58% of other Promo cards we track. It is at or near its highest price of the past year.
What makes this card unusual?
An ordinary 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 25% 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?
Fee exceeds raw price
A roughly $22.00 grading fee is 150% of the $14.62 raw price. Raw price plus fee comes to about $36.62, before shipping, insurance or selling costs. That is a cost comparison, not an estimate of a graded copy's value. 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.
