Value betting on the river?

[hurlyburly]

Didn't care for how this hand ended, had him on a lower spade draw, but I couldn't tell what he'd be willing to call with on the end here? Only showdown up to this point was 10-4o When I spiked a 10 on a paired-A board, so I thought I looked sufficiently LAGgy.

How many would go for the c/r against a coldcaller here?

Just make a value bet of 1/2 the pot and don't get cute. If villain has a smaller flush he'll likely reraise you and if the villain has tptk, two pair, a set, etc. he'll pay you off. I don't like checking because it look's like the guy maybe has a weak hand that he decided to call down and he's likely to check behind.
