Retro Frame / Borderless Mythics is one of 75 card types scored in The Card Investor, filed under Magic: The Gathering cards.
Appreciation 75 with liquidity 70 is the combination worth looking for: room left to run, and a market deep enough that you could act on a change of mind. It's also the combination that attracts the most competition, which is usually why accessibility is the score that suffers.
Accessibility of 50 means you'll pay somewhat over the sensible number but not absurdly so. Worth watching, because this score moves faster than any of the other three.
Set against the 5 Magic: The Gathering card types scored here, its appreciation of 75 ranks 5th of 5, liquidity 70 ranks 3rd, accessibility 50 ranks 2nd, and risk 30 is the 4th-lowest. The closest thing to it on the numbers is Commander Format Staple Foils, which scores 84 and 85 on the same two axes — if you're weighing one against the other, the difference is in the reasoning rather than the scores.
Two years gives the situation time to develop past its first impression, which is usually when the price is set by whoever shouted loudest. It also means two years of not touching it, including through the stretch where it looks wrong.
At 30, this is one of the calmer entries in here. Read that as relative: the floor under any card is whatever the next person will pay, and that number can move a long way in a month.
Every entry gets four separate scores instead of one grade, because a single grade hides the thing you needed. Full explanation in the guide: what Kabooms, Downtowns and Color Blasts are worth.
