Is this card interesting right now?
Ordinary - 53 out of 100
It ranks above 54% 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?
Sellers undercutting and firmer than most over 2 months
Median asking prices sit below the recent-sales market reference - sellers are pricing more aggressively. It slipped slightly behind the market over two months, but by less than most cards did.
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+0.7%
Past 2 months+6.8%
Past 4 months+26.0%
Is it expensive or cheap?
$9.61 - cheap for its set
At $9.61 it is one of the cheaper cards in its set - number 274 of 337 by price. It costs more than 89% of other Common cards we track. It is at or near its highest price of the past year.
What makes this card unusual?
An ordinary Common from a 24-year-old set
Common is a widely printed rarity - 12,380 tracked cards share it. The set is about 24 years old, so surviving copies in good condition get scarcer over time.
Could you actually buy or sell it?
Yes, with patience
The price changed in 34% 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 229% of the $9.61 raw price. Raw price plus fee comes to about $31.61, 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.
