Yes, there was a time limit on that - Philos are long gone (thats why they vanished completly from your "inventory") and I'm not sure if Myth could still be traded - if so you'll have to speak to Auriana in Mor Dhona...

Filling in tickets will get you nothing though I suppose - you wont get your Philos (aka some Sols for them) back because they no longer exist and it was announced a few times that they would be removed (I dont expect you to read patchnots while not playing but thats what SE will say I assume - "you have been warned"). I dont recall the exchange rate but it was very poor... like 1:10 or so? Which would mean: Your Philos would be worth 200 Myth, so 1320, so like 132 Sols... might be slightly better but I suppose you wont even get enough Sols for one piece of jewelry from that xD

Sorry to say so, but my best advice would be not to cry over spilled milk and run dungeons to get this new currency... it will stack up so fast that you wont even noticed that your old tomes are gone...
