Trent Ballard
Everything published on gunnar.cards carries this byline. Trent Ballard is a pen name — the editorial desk behind the site, not one person's government name.
Why this site exists
gunnar.cards is built around one player and every card he appears on. The questions that bring people here are always the same — which card is the real rookie, which parallel is worth chasing, whether a graded copy is worth the premium over a raw one — and they are surprisingly hard to answer in one place. This site answers them properly and keeps the answers current, because the market moves and a number typed into an article is stale the next week.
The perspective is a working collector's, not a press office's. Sorting, grading, buying and selling real cardboard is how you learn which products people actually rip, which parallels are genuinely hard to pull, and which "hits" are not worth the postage. What the byline stands behind is checkable: every price on this site is a live marketplace number, and every set fact is sourced rather than guessed.
How a page gets published
Five rules, applied to everything here:
- 1
No made-up prices — ever
You will not find a "book value", a price estimate, or a projected return typed into an article here. Card values move weekly, and a number written once is stale by the next weekend. Where the market matters, the page shows live marketplace listings with real current bids instead.
- 2
Availability is checked daily, not written once
Every product listed is re-checked against its live retailer listing every morning. Sold out gets labelled sold out rather than quietly left up, and dead listings are swapped or dropped automatically.
- 3
Card logistics over hype
Which set a card actually falls in, prospect auto vs. official rookie, parallel and refractor ladders, print windows — the details that are annoying to track down and stay true for years. That is the spine of the site; buying advice sits on top of it.
- 4
Money is disclosed on every page
This site earns through affiliate links (Amazon Associates and the eBay Partner Network) and display ads. Nobody pays for a ranking, a review, or a spot on a list, and no brand sees a page before it publishes.
- 5
Corrections get made, not buried
If something here is wrong — a set name, a rookie-year claim, a broken listing — send it in and it gets fixed, with the page date updated so you can tell.
