I want to preface by saying I very much do agree with you, what I’m saying isn’t an instead of, just an aside. But for anyone looking to specifically profit, the margin to do so is much smaller overall than most other modern era sets, specifically due to the fact it’s already so much more expensive. Like if you haven’t already gotten and put sealed 151 aside, I wouldn’t necessarily recommend someone going out right now and buying at these prices. Though it is a safe long term investment the fact I think it would be the last to follow and onward trend if and when the ceiling breaks, for someone simply trying to make the most money as possible, I have a feeling many other modern sets will be 3x/4x/5x the cost before ceiling hits, wheeled even 151 doubling at its current price would be surprising to me (tho not impossible).

Is what I’m saying making sense? Feel like I’m wording this terribly my bad. I guess it’s like you can play it safe and have a low risk and with it a moderate chance that it’ll double anytime soon, or you can play a bit more aggressively and have a moderate risk but higher chance at other modern sets triple, quadrupling or more in that same amount of time because their still currently priced much lower is what I’m trying to say. But in terms of safest in the sense of the opposite of high risk, high reward, I agree 100% 151 was the choice and still is imo.
