I don't think so. Craven wouldn't have any retail value unless it's 53 att, and even then good luck finding a buyer. Most people wouldn't be interested unless it's at least 55 att.
So the current pricing right now for cravens are 51 atk 3m(sell overnight), 5m(slower sale) 7luk+ Craven 52(haven't seen many of those, but 9 luk is especially nice and it will go for 10m easily) Craven 53 30m 54 45-50m 55 80-100m 56 150-200m Let me explain why cravens that are 51 atk are not worthless, people buy them for 2-3mill usually to 10% them and then 30% after, so they need around 30 cravens for 1 like that to be successful. that allows you to create a 61atk 5 slot for around fairly cheap. 55 atks are for big ballers, you would need to do the same with those to be worthwhile your time, only those you'd 30% from the start, but you already know that. So you personally wouldn't even bother with the 51s but alot would, in fact alot more would go for those than the 55s you see, and if u have 5 of those, the buyer will buy all of them most of the time if they are 51 +6 luk at least, for the reason above. I am 100% sure of these prices, as long as you have a decent spot. even fm22 or ch2fm2, you can sell those 51 within a night or two. I can see how a few months ago(i haven't played back then mind you, but it's just basic economics) nobody would want them as there weren't many new people and there was a lot less demand for cheap cravens, now there is. Same thing happens to overall luk 60%. I hope you get my point, and make sure before you comment on price checks not to mislead people.
