I came across this anvil on marketplace and went to check it out. It's in great condition but the gentleman is asking too much ($1750 usd). He claims the anvil and stand are 700 lbs, with the anvil itself weighing 500lbs. After seeing it, that claim is highly unlikely even though it is quite heavy. He said he picked it up after a paper mill closed its blacksmith shop decades ago. 

I think its a Fisher judging by the bolt holes on the base. It has no markings at all on it. Does anyone have an idea what brand or weight it could be? Or an offer I could give the guy? The face is 13" long, 5" wide, 13"tall, and overall 23" long. 

I can not say that is a Fisher or is not.  Here is a link to a post about a 250lb Fisher.   It is measures longer than what you posted, so infer what you will from that regarding weight.

Thank you for the spot on link ShoreB. It looks very similar in dimensions. 

At one time fisher did produce anvils that had a stick on emblem (Logo) instead of the cast in emblem we are familiar with. It would be hard to make an offer without knowing the actual weight and the base weight does not figure in the value. Sure wish Josh the owner of the Fisher Museum would see this thread, he is the resident expert on Fishers. You might take a look at his thread to get some better idea, maybe even send him a PM about your question.

I have a 250# Fisher anvil in slightly better condition than the one pictured where one of the former owners cut off the mounting lugs for some reason.  That being said, it is a great anvil and has worked extremely well for me.  As far as I know, there no real modern equivalent that has the combination of materials that intrinsically reduces the anvil ring without appreciably affecting surface hardness and resilience, mass in the "trunk" (so critical for efficiency), and rebound (arguably a evaluation standard rather than a critical parameter). The quiet aspect of the anvil was important to me as my shop is in a residential neighborhood and I don't want to alienate my next door neighbors. 

The anvil you are looking at is large enough far almost all work, unless you start making huge architectural pieces.  It will likely last another few generations if used with care.  Compare that cost over time with the purchase of a new high end cell phone...

That being said, in the condition I see from the photos I would likely try to purchase for closer to $1K.  I paid a bit more for mine, but it was pristine.

I've seen a couple of Fishers with the logo ground off for some reason, probably because a previous owner wanted to use the side of the anvil as a forging surface.

Fisher put a 1 3/4 hardy on their 500 & 600 lb anvils. I used to have a chart that listed the size to weight of their hardys, but can't find it.
