I'm a big Johnson Matthey collector myself and I can tell you I would definitely pay more for consecutive serial numbers if that was what I was looking for. When I'm looking online for collective JM bars I usually look for low and unusual serial numbers and consecutive serial numbers if there is more than one bar in the auction.
I would definitely not go to a local dealer. They would pay you usually under spot. From the serial numbers you have stated, they are from the last batch of Johnson Matthey bars minted in the late 1980s that had the "R" prefix. I bet they would go anywhere from $65 to $85 on ebay for both bars together depending on how bad the bidders want them.
