6th Anniversary Coins

So, I collected around 900 coins, never traded them in then left on vacation for almost a week, came back, saw the pomegranatestorm that the exploit caused while i was gone and didn't care much since it didnt affect me at all, now I've been hunting for lvl 64 maple weapons at roids/neo-huroids to trade them in for coins like at event's start, am I screwed if i keep them?
I never ever had a chaos or anything to do with it on my inventory



What do?
