With the BANK and LOCKER verbs now filling the role that these used to, is there any reason to hold onto these other then maybe as RP props?

I keep being tempted to toss mine in a barrel to reduce the clutter I'm carrying but have an uneasy feeling I might regret it if I do...

A severed gnomish hand crawls in on its fingertips and makes a rude gesture before quickly decaying and rotting into dust. A gust of wind quickly scatters the dust.

Do they actually let you do that? Premium "perks" can be tricky about letting you get a replacement, some don't allow it at all, and some you have to dispose with the right command to be allowed to get a new one.

I tossed mine and use the verbs regularly and haven't had cause to regret it. YMMV.
