When to Grade vs Hold Raw
Not every comic should be graded. The economic test: is the grading cost (CGC fee + shipping + insurance + opportunity cost of slabbing time) less than the expected value lift from market-recognized grading?
Submit to CGC when:
- The book is a key issue with a defined high-grade market premium
- The expected grade is 8.5 or higher for Silver/Bronze, 6.0 or higher for Golden, 9.6 or higher for Modern
- The book has clear structural integrity — square spine, no major chipping, no color-breaking ticks
- The book is not a known restoration risk (Golden Age in particular: many books were professionally restored decades ago without disclosure)
Hold raw when:
- The book has only emotional / collection value (not a key, mediocre condition)
- The book is above 80% likely to come back at a grade below the value threshold for its category
- The user does not need the slab for sale / insurance / display purposes
- The book is Modern and the population at the likely target grade is already 10,000+ (the slab doesn't differentiate)
CGC's standard service has been ~$30-50 per book at the lowest tier (60+ day turnaround) with tiers escalating to several hundred dollars for fast-track / "express" / "walkthrough" service. The walkthrough tier is appropriate for high-value submissions; standard is appropriate for most.
Pressing Economics
Pressing applies controlled heat, humidity, and pressure to a raw comic before grading. The mechanism removes:
- Non-color-breaking spine roll — the slight curve from years of storage
- Surface ticks and small dents — pressure flattens them
- Light bending defects — corner bumps, finger creases that haven't broken color
- Some chipping flat-ironing — corner chips can press down (though missing material doesn't return)
Pressing does not fix:
- Color-breaking creases (the ink has cracked; pressing doesn't restore it)
- Missing material (chips that have detached)
- Stains, tape, glue residue
- Restoration that has been previously applied (pressing through restoration can make it more visible to graders)
The Economics — Worked Examples
Example 1: Bronze Age key, Hulk #181, raw, estimated grade 9.4
- Pre-press grade estimate: 9.4
- Post-press grade estimate distribution: 9.4 (50%), 9.6 (35%), 9.8 (15%)
- Market values: 9.4 = $25K, 9.6 = $42K, 9.8 = $90K
- Pressing service: ~$50 plus return shipping
- CGC submission (standard tier on a high-value book → typically Express tier): ~$200
- Total round-trip: ~$300
- Expected value lift from press:
- 9.4 stays: 0 (no improvement, but lost the press fee — $50)
- 9.6: +$17K
- 9.8: +$65K
- EV = (0.50 × 0) + (0.35 × $17K) + (0.15 × $65K) − $300 = $15,375 expected
- Strong positive EV; press the book
Example 2: Modern key, Walking Dead #1 raw, estimated 9.6
- Pre-press grade estimate: 9.6
- Post-press grade estimate distribution: 9.6 (60%), 9.8 (40%)
- Market values: 9.6 = $600, 9.8 = $2,500
- Pressing + grading round trip: ~$200
- EV = (0.60 × 0) + (0.40 × $1,900) − $200 = $560 expected
- Positive EV; press the book
Example 3: Silver Age non-key, Amazing Spider-Man #88 raw, estimated 6.0
- Pre-press grade estimate: 6.0
- Post-press grade estimate distribution: 6.0 (70%), 6.5 (25%), 7.0 (5%)
- Market values: 6.0 = $120, 6.5 = $140, 7.0 = $180
- Round trip: ~$120
- EV = (0.70 × 0) + (0.25 × $20) + (0.05 × $60) − $120 = −$112
- Negative EV; don't press, sell raw
Crackouts and Resubmissions
A crackout breaks a CGC slab to recover the raw book; resubmission lets it be regraded. The math is similar to pressing-from-raw, with two added complications:
- The downside risk is non-zero — a CGC 9.6 cracked and resubmitted may come back at 9.4 if a fresh grader sees it differently
- Multiple submissions accumulate slab fees — chasing a grade across 3 resubmissions can erode the EV meaningfully
Crackouts are most productive when:
- The slab is under-graded relative to peer comps (you've inspected and the grade looks conservative)
- The market spread between current grade and target grade is >4×
- The user can absorb the variance (this is not the user's only copy)
The Restoration Disclosure Discipline
Restoration is legal and routine for high-value Golden Age and Silver Age books. The ethics center on disclosure:
- CGC will detect restoration in nearly all cases — color touch, piece replacement, tear seal with material added, bleaching, recoloring
- A purple CGC label ("Restored") drops value 50–80% vs. universal at the same grade
- Selling a restored book as unrestored is fraud — the secondary market is unforgiving
Conservation is the related but distinct concept:
- Dry pressing (no chemicals, no material added) — generally classed as conservation
- Cleaning surface dirt without chemical contact — conservation
- Sealing an open tear with archival tape from behind, no material added — borderline; CGC may class as conserved
- Color touch to "improve appearance" of a faded spine — restoration (material added)
A light blue CGC label ("Conserved") trades closer to universal than to restored — typically a 10–25% discount rather than the 50–80% restored discount. The collector should know which kind of work has been done.
The Meyers v. CGC Case (2024)
A Philadelphia jury awarded $10M against CGC for falsely accusing a restorer of work he didn't do. The lesson: CGC's restoration calls are judgments, not infallible verdicts. If you believe a CGC restoration call is wrong on a piece you own, formal challenge is possible — though expensive and uncertain. Get an independent expert opinion before challenging.
CGC vs CBCS
CGC dominates for liquidity. CBCS books trade at 10-20% below comparable CGC at the same grade for most issues. There are minority arguments for CBCS:
- CBCS provides subgrades in their slabs (centering, edges, corners, surface)
- Some collectors prefer CBCS slab design
- CBCS has historically been somewhat less punitive on certain edge cases
For market liquidity, CGC is the answer. For purist collectors who value subgrades, CBCS has a niche.
PGX
PGX is the third major slabber. PGX-graded comics trade at significant discounts to CGC. Many collectors will not pay any premium for a PGX slab; the company has had quality-control disputes over the years. For market purposes, treat PGX as raw.
Connoisseur ─── Pressing Is a Reversible Tradition
A well-pressed comic looks like a comic that was treated gently for fifty years. The defects pressing removes — minor spine roll, small ticks, finger bends — are the residue of how the book was handled, not damage to the underlying material. Pressing returns the book to closer to its as-printed state. Done poorly, pressing risks creating ripple lines or accelerating natural fading; done well, it is invisible. The ethical and aesthetic line is that pressing redistributes material; restoration adds material. The first is curatorial; the second requires disclosure.
Allocator ─── Press Before Submission Almost Every Time for Bronze and Older
The pressing fee is $30–50; the round-trip cost is $200–400 including grading. The expected value lift on a Silver or Bronze Age key with reasonable structural integrity is in the high hundreds to low thousands of dollars. The EV math runs heavily positive for almost any Silver/Bronze key estimated at 8.0+ before press. For Golden Age the math is even stronger because the grade-tier spreads are wider. The systematic policy: press before grading on every Silver/Bronze/Golden Age key estimated at 7.5+ pre-press. Skip pressing on Modern unless the estimated grade is 9.6+ pre-press.
