I hear a lot about the disappointing selling prices and interest lack in nice old pw's. The present attitudes remind me of 1959 when my wife worked at an old small town bank that was clearing the vault of silver dollars. Many acquired from mints before 1900. No longer in demand for users like the pw is today. So we bought for $1. each a bunch mostly unused selected for rarity and condition. Got a collection of 70 different plus a tire chain bag full left in my car while moving to a new job location. This was not an inside deal, others had same opportunity, but did not consider it so. I still have original collection and rare date ones. See the comparison? Nobody wanted the common silver dollars at that time. Even the rare ones were cheap. Imagine how much the selected 70 different has exceeded inflation.
50 years ago silver $ in same situation as pw today. However, interest by age 40 and younger in pw mechanics, art, and precision work is increasing in my experience. Valuations are tending towards that for coins where new condition sells well and ordinary is ignored. Prestige auction houses still get outrageous prices for rare pw as they always have for coins. Hoard (bad word) rather than sell. The demise of the pw is greatly exaggerated.
