Start with the name on the holder
A listing can use “CAC” casually even when the service distinction matters. Before comparing two prices, look at the full holder photograph. Read the grading company, numerical grade, designation and certification number, then identify whether the approval is an applied sticker or part of a CACG label.
The archival PCGS illustration above shows the stickering arrangement: coins in PCGS holders with green CAC stickers. It predates CACG encapsulation and does not show a CACG holder. The old registry interface in the background is not a guide to today's website.
Two services, different roles
CAC's official services overview dates the stickering service to 2007 and the grading service to 2023. The first supplies an additional assessment of a coin in an existing eligible holder. The second supplies the grade and encapsulation itself.
| What you see | What it identifies | What to read next |
|---|---|---|
| PCGS or NGC holder with green CAC sticker | CAC approval at the stated numerical grade | The underlying grade, designations and certification record |
| PCGS or NGC holder with gold CAC sticker | CAC regards the coin as meeting its approval standard at least one numerical grade higher | The actual grade remains the one printed on the existing holder |
| CACG holder with built-in emblem | CAC's own grading and encapsulation service | The CACG label and certification record |
CAC says its own holders cannot be separately stickered; the built-in green emblem serves that role. Do not assume a CACG coin is missing an approval merely because you cannot see a removable sticker.
Green does not mean only the very best
Under the official stickering FAQ, green approval includes coins CAC considers solid or high-end for their grade. It is not a promise that every approved coin is the single finest-looking example at that level.
It also does not turn the label into a new grade. If the holder says MS64, the green sticker does not relabel it MS65. CAC explains that its stickering assessment uses the numerical grade rather than separately endorsing a plus suffix. Read each part of the label for what it actually states.
Gold is not a guaranteed upgrade receipt
A gold sticker indicates that CAC considers the coin worthy of green approval at least one numerical grade higher. That is a stronger assessment than green approval at the printed grade, but the existing label still states its original grade.
Do not turn that distinction into a guaranteed result from a future submission. Different services and submission choices involve their own evaluations. If your real question is whether to change a holder, our crossover, regrade and reholder guide explains the separate service decisions.
What an absent sticker cannot tell you
An unstickered PCGS or NGC coin may never have been submitted to CAC. Even when a coin was reviewed without receiving approval, that does not automatically prove the original grade is wrong. Avoid a seller's shortcut that treats every unstickered coin as rejected or inferior.
Ask for evidence if a listing makes a specific submission-history claim. A lookup is useful for verifying an approval record, but absence of a record is not a complete history of the coin. Do not fill that gap with an assumption.
Compare the coin and the transaction
Neither sticker color nor holder brand supplies a universal percentage premium. Compare actual coins of the same date, mint, variety and grade, then account for eye appeal, surfaces, designations and sale terms. A single unusually strong auction result does not establish what every similar label should bring.
For a listing you are considering, save full front-and-back holder photos and the seller's description. Read the certification information through the grading service's official verification page, and check that the visible coin and label are consistent with the record. A matching number is one check; it does not replace examining the item offered.
GreatCollections' terminology guide is a useful example of how an auction venue separates the two services. If another listing uses ambiguous shorthand, ask which holder and approval it actually includes before making price comparisons.
A quick reading order
- Identify the grading company on the holder.
- Read the coin identity, numerical grade and designations.
- Identify an applied CAC sticker or CACG's built-in emblem.
- Check the relevant certification or approval record.
- Compare the photographed coin, seller terms and completed sales—not just a sticker color.
If labels themselves are unfamiliar, begin with our PCGS and NGC label guide. Treat approval as useful information to interpret alongside the coin, rather than a substitute for reading the whole listing.
