Odd for someone to appraise it twice simply because someone appraised it differently or less.
The rationale that it is a 90's year (I assume you meant 1900's or 20th century) therefore automatically an $xx,xxx.xx name is hard to buy, from my perspective.
The market may be strengthening for the "right buyer" but...the market (or marketability) for a random year date is less than a significantly historic date.
There is not a person on here that can really quote a significant even that occurred in 1946 without using some resources.
A random date may have significance to someone born in that year.
Granted, there is a nice market for NNNN domains and NNNN is easy recall.
But claiming it is worth xx,xxx to the right buyer is so vague in concept.
Everything may be worth xx,xxx to the "right buyer".
This so called "right buyer" might be someone willing to pay $xxx,xxx.xx or even seven figures.
Really is no definition to the "right buyer" other than being just a fictitious entity.
We all want that "right buyer" to come knocking on the door.
But for now, how many "right buyers" are you (or the owner of this name) going to turn down offers in the x,xxx range waiting for that "right buyer"?
