CCI 04.0479 'linear' series, VA 1925-1. The earliest of these three, perhaps from c. 20 AD, and a little rarer, with about 60 recorded here. Again there is a coin in the BM from the same pair of dies, BMC 1783. There are a couple of rather unusual features to the dies - although not clear on your example because of the position it has been struck, there appears to be no V on the end of CAMV, and there's also a mark - perhaps some kind of privy mark - after the CVN on the reverse, you can just see the top of what looks like a letter I between the N and the horse'sfront legs on your coin.
