TCG Valuations Managing Director and Certified Valuer Jonathan Marin has been featured in the October 2026 edition of Money Magazine, discussing the rapidly evolving market for trading cards and collectables, the importance of professional valuations, and the risks and opportunities facing collectors.
The four-page feature, titled “Rare breed” and written by journalist Tom Watson, explores Jonathan's journey from childhood collector to specialist valuer, alongside the growing recognition of trading cards as valuable collectible assets.
Published in one of Australia's established personal finance magazines, the article examines what makes certain trading cards valuable, how professional valuations are conducted and why collectors should understand the difference between rarity, condition and market demand.
From Childhood Collector to Certified Valuer
Jonathan's interest in collectables began in childhood, with video games and trading cards eventually developing into a professional specialisation.
Today, as Managing Director of TCG Valuations and a Certified Valuer with the Auctioneers and Valuers Association of Australia (AVAA), Jonathan works with collectors seeking professional assessments of trading cards and other collectables.
The Money Magazine profile explores his collecting background, the establishment of TAG Collectibles, the acquisition of TCG Grading and the development of TCG Valuations.

What Makes a Trading Card Valuable?
A central theme of the interview is the importance of understanding the factors that influence a trading card's market value.
While high-profile sales of rare Pokémon cards have attracted international attention, not every old or unusual card carries significant financial value.
Professional valuation involves examining multiple factors, including:
-
Authenticity: Establishing whether the card or collectible is genuine.
-
Condition: Assessing centering, surface quality, corners and edges.
-
Rarity: Understanding production quantities, variations and population data.
-
Market demand: Examining collector interest and recent comparable transactions.
-
Provenance: Considering documented history where relevant.
The article also explores the distinction between grading and valuation. While grading assesses a card's condition and authenticity, valuation considers its monetary worth within a defined market and for a specified purpose.
Why Professional Trading Card Valuations Matter
As the market for Pokémon cards, sports cards and other collectables continues to develop, professional valuation services are becoming increasingly relevant.
Collectors may require valuations for insurance, estate administration, asset division, dispute resolution or other formal purposes.
In the interview, Jonathan explains that the valuation process goes beyond simply checking online asking prices.
It involves examining the asset, understanding the purpose of the assessment, evaluating relevant market evidence and applying a defensible valuation methodology.
For valuable collections, accurate documentation and appropriate insurance arrangements can also play an important role in protecting owners against financial loss.

Collecting, Investing and Understanding Risk
The feature also considers the increasing popularity of trading cards as alternative collectible assets.
Although some rare cards have achieved substantial prices, Jonathan cautions against treating collectables as a guaranteed pathway to investment returns.
Unlike conventional financial assets, trading cards operate in markets that can be highly speculative, with prices influenced by changing collector preferences, supply, demand and broader economic conditions.
His advice to new collectors is to develop a genuine understanding of their chosen collecting category, research the market and avoid purchasing solely on the expectation of rapid financial gains.
As Jonathan explains in the article:
“It's collectors who genuinely enjoy immersing themselves in their collectables that are more likely to succeed over the long run.”
