I disagree with determining a person's gold worth based on rares. Collectibles are subjective and there are many factors that determine value, and they never hold solid value like a lux item does (you can't liquidate fashion by selling it to a vendor). If Maysin desperately needed a large amount of gold in one week, he would never ever net 150 million by selling everything he owns. That's because most of what he owns can not be liquidated, it has to be sold to other players. There simply is not over 50 million gold in circulation on Sulis. Not only that, but there is absolutely no market for most of the stuff he owns. There aren't people actively seeking 100% mounts who actually have the means to afford it. That's because the new mount system makes all of Maysin's mounts mostly just novelty. Who actually cares?
I'm not sure how you got the "150 million" number in the first place. Is that how much he told you he was worth, or was it just a bad joke? You people do realize how much 150,000,000 is, right? That number is no where remotely close to any good estimate of the total gold currently in circulation on Sulis. Now look, items that only have value when sold to another player can't be sold for more gold than the server has in circulation, because that amount of gold simply doesn't exist. Never mind having to spend time finding buyers who actually want/can afford the stuff.
I also disagree with someone determining their own collection's net worth. Collectibles are subjective to opinions and aren't worth the same to everyone. If you own a white lugh mask, it's probably worth more to you than it is to me. Otherwise I would have paid more than you did to acquire it. You should ignore people who tell you what their collection is worth, it's all subjective. At the end of the day, those type of items are only worth what someone is willing to pay.
Now that I've explained why nobody can be worth more gold than exists in any given server, let's debunk the myth Maysin and Patato have any legacy truly worth mentioning.
It takes around 500 super knowledge or super combo elixirs to reach level 220 (rough estimate). It probably takes 5-6 million gold to fund all the pots, idols and elixirs required to go from 1-220. Let's not even consider the amount of time someone would need to invest, ok?
Maysin and patato currently have one character that is actually level 220 (Maysin). This rogue isn't even endgame though, because don't forget he only has DL weapons. There are people in this game, myself included, who have more than 4 toons above 220 with full EDL and can literally solo almost anything. If Maysin offered everything he owns in exchange for an EDL rondel, it would never happen. There are many things gold can't buy, which people like me already have. And considering every rational person dislikes Maysin and patato, they'll never get such items. Never mind that, I personally don't believe Maysin could even make the investment required to level more toons to 220.
