FWIW, new quality anvils go for $5 - $7 per lb. Centaur Forge in Burlington, WI was at one time and probably still is the largest purveyor of anvils in the US.
https://www.centaurforge.com/Anvils/departments/141/ Bill Pieh was the founder and owner of Centaur Forge. I first met him when I was a member of the Upper Midwest Blacksmith's Assn. in the '80's. Here is an interview with Bill by Anvil magazine.

An interesting story about Bill. In addition to his love for blacksmithing and horseshoeing, he was also a private pilot. He had a twin engine plane, Beechcrft, as I recall, and would fly a plane full of supplies to trade shows around the country. On one occasion he had a load of anvils in the back of the plane. As it turned out, he hadn't bothered to secure them properly and when he hit some turbulence, they shifted forward, upsetting the plane's trim in the process. He managed to correct the issue and make an emergency landing. I imagine it took a few years off his life though. He told yus that he would never again fly with unsecured cargo.
Used anvils typically go from $3/lb and up depending upon condition. Pristine used anvils can exceed $10/lb. Occasionlly, anvils can be found for around $1/lb., usually some farm auction or a widow cleaning out the shed. If the anvil can be identified as a quality brand and is in decent condition, it would be a steal.
Most of the used anvils show evidence of heavy use. Edges are broken, hardy holes have chipped edges, the face is swaybacked, etc. This doesn't mean that the anvil be used can't do quality work. Edges can be repaired by welding. The edge should be pre-heated before welding. I forge welded a new steel face on an early 19th century Mouse Hole anvil, using a piece of semi leaf spring for the face. The anvil also had a broken horn and I fashioned a new horn and welded it to the anvil body. I use that anvil to this day .
As to the original post, I believe this is what the article looks like.

Also, an anvil's utility comes from its mass. Aside from just dinking around, my preference would be an anvil in the 100+ lb. range. Something that I'm not afraid of damaging using a 4 lb. hammer or 10 lb. sledge on.
