Lucky Coins: Any other way?

[Astarin]

First off, I know you obtain Lucky Coins by completing the Phantasmal World quests.

But is there any other way of obtaining them?

I ask, because I recently completed my first PW #4 run with my RAcaseal. In fact, it was the first PW quest I'd ever finished with her. I thought "yay, lucky coin, I'll go play roulette".

When I got to Gallon's Shop and tried, the game told me I have 33 lucky coins! Hot diggity! ...so where'd these come from? None of my other characters do PW quests, and I've only finished one with her once.

I have done plenty of partial runs... am I getting coins from these, or is there another source?

there were reports of a random amount of coins being stored on a char before. and no, the how and why is not clear yet.
overall, grats

Some type of game glitch occasionally gives large amounts of lucky coins - so lucky you

Haruna once got something like 69 lucky coins after a PW4 run.

I have never been lucky with lucky coins
