Boz,
Last year I helped my mom sell some coins after my dad passed away. It's hard to weigh the money vr. effort/time.
For my mom, the effort/time was more important. She didn't want to drag out the process. Of course she asked me to try to get top dollar for them, but she wasn't going to hold out for it.
If the coins have silver or gold content, you can sell them for the metal content at a gold and silver place, and those have set prices per ounce, so you really only have to rely on a correct determination of silver or gold content.
Best of luck
