The old Folio Society edition (the one in a slipcase) of A Christmas Carol is beautiful. It’s out of print now but I managed to pick it up secondhand for about £15 from eBay so it’s worth keeping an eye out.

Someone on YouTube did a flip through showing the inside https://youtu.be/14oHh_qhhoQ

The Calla edition is also really lovely. Again, a good mix of colour and black & white illustrations. It’s also easily available in the US: https://www.amazon.com/Christmas-Carol-Calla-Editions/dp/1606601210/ref=as_li_ss_tl?ie=UTF8&linkCode=sl1&tag=metropolitanmama-20&linkId=f4d02bcb2178ffd1d63e2b41a50afd9f

The Mystery of Edwin Drood? The link is about some adaptation of Dickens' novel, called Drood by Dan Simmons. But it seemed to match your description of "man with a top hat".

Or could be Our Mutual Friend also. Just making guesses here based on book covers I find!
