If you take a small hammer and tap the steel hardened face all over to see it it rings clear, that will tell if the forge welded on steel face is intact. If the ring sound changes a lot from front to back or you hear any buzzing sound, that means the face has become de-laminated and the anvil is probably only worth scrap prices, not an anvil that will be good to forge on. The rebound is checked with a steel ball bearing about a half inch diameter. Drop it with a ruler to use as a gauge from the 10 inch mark and see how far the ball returns. that will give a percentage of rebound 8 inches will be excellent 80% anything below 6-7 inches will be poor and indicate the face plate has been heated and lost it's hardness most likely due to a fire.
The anvil looks to be in very good condition and in your area good anvils go anywhere from $2.00 or $3.00 per pound maybe more.
