Difficult To Identify And Know Value. Seeking Help

To the CCF

In order to help you, we are going to need clear pictures of both sides of each coin you may have a question about.
Please post each coin on its own thread with the proper heading and in the right forum.
There are many knowledgeable people here that should be able to answer any questions you may have.

While I echo the "pictures please" of the others, I can tell you that the "crone bane" half penny is likely one of the many Conder tokens of the late 1700s. These tokens are worth a few dollars to $30 or more depending on the condition and variety.

I suspect that your grandfather picked up mostly circulating coinage of the countries he visited.

While the vast majority of that would be quite common there may be a few gems/ silver coins.

What it the total weight of all the bags?

I do not recommend photographing each coin individually, not yet. It would likely be a waste of time to photograph hundreds of common coins.

For us to get a sense of what you have, I suggest photographing a "group" picture of the contents of each bag so that we can see most of the coins.
