The Newman Numismatic Portal is hosting a FREE symposium from 10 am to 7 pm each day March 19-21. You have to register (again free) and then you will be able to attend any of the presentations. Here's a list of the presentations-pretty much something for everyone. https://nnpsymposium.org/schedule (For some reason, I couldn't cut and paste an operable link into this message so you'll have to C&P the address.)
