there are lots of websites with used tackle particularly Hardy mostly out of the UK As an example:
http://www.classicvintagefishingtackle.com/hardyreels.htm.
You'll notice value is associated with aspects that make the product somewhat unique. If it's numbered, if it's a limited edition, if it is unused with all literature, bag/box etc,.
Try googling specific products ie Hardy Marquis #5 for sale.
As far as the reels they may have some value. It's also a matter of what it's worth to you. I wouldn't pay more than $50 for a reel in that shape besides I have a Marquis and owned other Hardy's of similar vintage - nothing to get excited about. The pre Ww2 stuff was different but hard to find and costly.
Rods from the 60s would be valuable if they are split cane. Glass rods may have some value. Glass (unlike graphite)does not age well
Fifty year old rods may not be suitable for fishing unless you like breaking rods.
