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 - 93 out of 100
It ranks above 93% 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?
Very steady price and sellers holding firm
The price moves in small, calm steps rather than lurching around. Median asking prices sit above the recent-sales market reference - sellers are holding firm on price. This has been the strongest historical price signal in this market. Working against it: asking prices are more spread out than on most cards, so what you pay depends on which listing you pick.
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.

Is it expensive or cheap?
$101.83 - expensive for its set
At $101.83 it is one of the priciest cards in its set - number 19 of 464 by price. It costs more than 83% of other Rainbow Rare cards we track. It is at or near its highest price of the past year.
What makes this card unusual?
Rainbow Rare - genuinely scarce
Only 36 of the cards we track are Rainbow Rare - under 0.1% of them. 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 20% of our checks over the past year across 364 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?
Material fee versus raw price
A roughly $22.00 grading fee is 22% of the $101.83 raw price. Raw price plus fee comes to about $123.83, 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.
