# Slab classification

This refers to the grading and encapsulation process where a third-party service, like PCGS or NGC, assigns a numerical grade to a coin and seals it in a tamper-evident holder, known as a slab. The grade reflects the coin's condition—everything from mint state to heavily worn. For resellers and collectors, the slab is crucial because it provides an objective, verifiable assessment of the coin's quality, removing subjective opinion. A professionally graded coin commands a significantly higher price than an ungraded equivalent, as the grade acts as an insurance policy against misrepresentation. Always verify the grading service and the specific grade number before purchasing, and always inspect the slab for any signs of damage or tampering.

## What it means
Slab classification is the process where a recognized third-party grading service (e.g., PCGS, NGC) assesses a coin's condition and places it in a sealed, tamper-evident plastic holder, or "slab." The service assigns a numerical grade, which is a standardized, objective measure of the coin's preservation—from Mint State (MS) to heavily circulated (G). This numerical grade replaces subjective opinion. The slab itself is the verification mechanism; it guarantees the coin's stated grade has been authenticated by the grading company.

## What it does to price
The grade is the primary driver of value. A professionally graded coin typically commands a premium ranging from 1.5x to 5x the price of the same coin loose (ungraded), depending on the rarity and the grade achieved. A coin graded MS-65 will sell for significantly more than an identical coin graded MS-60. High-grade coins (e.g., MS-67 and above) see exponential value increases. Conversely, a coin with a low grade (e.g., AU-50) may fetch less than 50% of the value of a comparable, higher-graded specimen. For instance, a common silver dollar might sell for $20 loose, but if graded MS-65, it could easily reach $100-$150.

## How to spot it
Authentic slabs feature unique, serialized labels affixed by the grading company. The label must match the coin's visible features. Common issues include "re-slabbing," where an old, low-grade coin is placed into a new, high-grade holder. Look closely at the slab’s seal integrity. Sellers sometimes photograph the coin *before* grading; these photos are useful for comparison. A common mistake is confusing the *grade* (e.g., MS-63) with the *slab type* (e.g., a specific protective holder). Always confirm the grading service logo matches the label.

## Buying smart
Paying a premium for a slab is justified when the coin is rare, high-demand, or when the grade is necessary to meet a specific collection standard. If the coin is common or the grade difference between two comparable examples is marginal (e.g., MS-62 vs. MS-63), the premium may not be worth the cost. A fair deal involves the premium being proportional to the grade jump. If a seller is asking for a massive premium for a low-grade slab, the coin is likely overpriced or the grading is questionable.

## Selling smart
Presenting a coin in a slab is the single most effective way to maximize sale price. The slab acts as instant third-party validation, which removes buyer hesitation and reduces negotiation room. When listing, the grade number and the grading company (e.g., "NGC MS-65") must be prominently featured. The slab itself is the premium feature; a photo clearly showing the certified slab is worth more than several descriptive paragraphs about the coin's condition.
