Short answer: no. If you could know exactly, the crash would be traceable.

But: we have something called "keyset epoch". If it's enough to know that ecash was minted during a time period in which a specific keyset was active (can be rotated once a week for example) that would work!

Store can issue ecash from keyset A for one week, rotate to B and issue, rotate to C etc..

All wallets can handle wash from multiple epochs. Nice thing about this is that you can also invalidate very old ecash (dead customers).
