Andrew Eeten’s Tips for Grading and Valuing Sports Cards: What Every Collector Should Know

Written by Jimmy Rustling

Sports card collecting has grown into more than just a hobby; it has become a serious market where condition and authenticity play a vital role in determining value. Grading services provide collectors with a standardized system to evaluate and authenticate cards, making transactions more transparent and reliable. Well-graded cards command higher prices, but Andrew Eeten emphasizes how even minor differences in condition affect their value.

Understanding the grading process, key factors that affect a card’s score, and the best practices for storage can help collectors make informed decisions. Knowing when to grade a card is essential, as grading fees can outweigh potential returns if a card isn’t valuable enough. Proper preservation techniques also ensure that cards maintain their condition over time, protecting them from environmental damage. By staying informed about market trends and making smart choices, collectors can build a valuable collection while maximizing their investments.

The Role of Grading in Sports Card Collecting

Grading plays a crucial role in determining a sports card’s authenticity and condition, which directly affects its desirability among collectors. A professionally graded card provides buyers and sellers with a standardized evaluation, making transactions more transparent. Without grading, card values can be highly subjective, leading to disputes over condition and worth.

Several reputable companies specialize in grading, with PSA, BGS, and SGC being among the most recognized. Each follows strict criteria to assess centering, corners, edges, and surface quality. A card graded by one of these companies is often viewed as more reliable in the market, increasing its potential resale value.

Raw cards, or ungraded ones, can still hold significant worth, but their value often fluctuates depending on buyer perception. In contrast, a card with a high professional grade provides confidence to collectors and investors. A gem-mint rating can turn an ordinary-looking card into a highly sought-after piece, especially when it features a legendary player or a rising star. Some collectors even focus exclusively on high-grade cards, knowing they hold long-term investment potential.

How Grading Affects Card Value

The grade assigned to a sports card can significantly impact its market price. A high-grade card, especially one rated Gem Mint or Pristine, often commands a premium due to its near-flawless condition. Collectors and investors are willing to pay more for cards that have been professionally evaluated and certified, as they carry a level of trust that raw cards do not. Even slight differences in grade can mean hundreds or even thousands of dollars in value, particularly for rare or vintage cards. This is why high-value cards are almost always sent for grading, as the potential return often outweighs the grading cost.

Market trends and player performance also influence a card’s worth. A rookie card of a rising star graded as a PSA 10 can skyrocket in price if the player starts breaking records or wins major awards. On the other hand, a lower-graded version of the same card might not appreciate as quickly, as collectors prioritize top-condition pieces. This is why many collectors carefully weigh the potential return before deciding to grade a card, knowing that condition plays a crucial role in long-term value.

Key Factors in Card Grading

When a card is sent for professional grading, experts evaluate multiple aspects to determine its final score. Centering is a major factor, as collectors prefer cards with balanced borders rather than ones that appear off-center. Edges and corners are closely inspected for signs of wear, as even minor imperfections can lower the overall grade. Surface condition is another crucial element, with scratches, print lines, or discoloration potentially reducing a card’s desirability. Some cards may look flawless to the naked eye but show micro-scratches under magnification, which can impact their final rating.

Certain flaws are common in older cards, making pristine vintage pieces particularly valuable. A 1952 Mickey Mantle card with sharp corners and clean edges is considered a rare find, as most cards from that era show signs of handling. Modern cards, on the other hand, are expected to be in near-perfect shape straight from the pack, which means even small factory defects can impact their grade. Those who familiarize themselves with grading standards often have a better chance of predicting their card’s final score before sending it in.

Determining Whether to Get a Card Graded

Deciding whether to grade a sports card depends on several factors, including its condition, potential market value, and personal collecting goals. Some collectors focus on preserving sentimental pieces, while others see grading as a way to maximize resale profit. If a card is already in near-perfect condition and features a high-demand player, grading could greatly boost its price. On the other hand, lower-value cards might not justify the cost of professional evaluation. Cards from popular sets or limited print runs tend to benefit the most from grading, as demand often drives up their value.

The cost of grading services varies depending on the provider and the turnaround time selected. If a card is highly sought after, having it professionally graded can add legitimacy and make it easier to sell. However, there is always a level of risk involved—if a card receives a lower grade than expected, it may not yield the return a collector anticipated. Weighing the potential benefits against the expense is crucial before submitting a card for grading. Some collectors choose to pre-screen their cards, sending only the ones they believe have a strong chance of receiving a high grade.

Protecting and Storing Your Collection

Proper storage is essential to maintaining the condition and value of sports cards, whether they are raw or graded. Cards left unprotected are more susceptible to damage from dust, humidity, and accidental handling. Many collectors use protective sleeves and top loaders to safeguard their investments, while high-value cards are often placed in slabs after professional grading. Some even go as far as using UV-protected cases to prevent fading from light exposure.

Environmental factors play a prominent role in long-term preservation. Excessive heat or moisture can cause warping, fading, or surface deterioration, which ultimately affects a card’s grade and market appeal. Keeping a collection in a temperature-controlled environment with minimal exposure to light ensures that cards remain in top condition for years to come. Serious collectors go a step further by using fireproof storage cases or locked safes to protect their most valuable pieces from unforeseen risks. Insurance coverage is another option for those with particularly high-value collections, providing added peace of mind.

Making Smart Decisions as a Collector

Building a collection requires research, patience, and an understanding of market trends. Prices fluctuate based on player performance, demand, and overall industry shifts. Collectors who stay informed about recent sales data and grading trends are in a better position to make strategic purchases and sales. Following auction results, joining collector forums, and networking with experienced buyers can provide valuable insights into the market.

Buying and selling cards involves more than just chasing big names. Some of the best investments come from identifying undervalued players before their market value spikes. Those who take the time to study the hobby, engage with fellow collectors, and make informed decisions often see the greatest long-term success.
