I do not say you cleaned because I do not think you are 95 years old to own this coin from the born. So is no accusation directed to you. The coin could not wrote the memories book.
For the value? I am not expert on this. Manny collectors like those coins and collect. It is a market for those coins. Sure a premium apply to this coin. How much? I will let the price specialist here to pronounce. For me from technical and material point of view it is a nice example of material (metal) aging. Just to understand a little bit. In 1962 the Mint Director ordered that from August 1 the coins alloy to be change to Brass (95Cu, 5Zn) for two reasons: 1. The cost of the Tin and 2. Accumulation of the coins by collectors due to material defficiences, specially exfoliation and planchet cracks (Lams)
Let see the prices.
