Like Lewis (great advice there), I say this a lot as well……
One of the best ways to start developing an “eye” if you cannot physically handle a lot of pieces is to study past auction results. Usually you get a few decent images and can often see the price they sold for, when and where they were sold etc. Images can be enlarged if of sufficient quality enabling the finer details to be examined. You will not learn everything but you will start to be able to discern what “quality” looks like and what quality costs.
It’s just my opinion and others will disagree but I think it’s far more important to recognise quality, both in artistry and manufacture than it is to chase Mei.
It’s the same principle that is applied to swords……buy the item, not the Mei
A good place to start….(and your tsuba is fine around that price imo)
