1896-P Morgan Silver Dollar PCGS AU + Gorgeous Rainbow Toning,

Description: This 1896-P Morgan Silver Dollar has a beautiful rainbow tone and strong strike. The coin has been certified by PCGS, About Uncirculated, Detail. (cleaned) Multi - Color toning is a Rare and delightful combination of variables. The surface and sub - surface reflectivity can be affected by exposure to reactive elements and extended time to create a surface that " Bends " the light that is reflected. This "Bending" or REFRACTION causes the different frequencies to bend in slightly different angels resulting in the separation of the frequencies (colors) in white light. This rare 1896 Morgan silver dollar is stunning. With its ultra-violet tone and PCGS certification, clearly a unique artifact. The coin was struck in Philadelphia and has a business strike type. It has a fineness of 0.9 and is composed of silver. The coin is circulated and has a denomination of $1. It is a true gem. Don't miss your chance to add this beautiful anomaly to your collection. © Government of Canada, Canadian Conservation Institute. CCI 120260-0299 Figure 2: As light hits the silver sulfide tarnish layer, some of it reflects off the top surface, and some of it passes through and then reflects off the underlying silver layer. These two different paths for the light result in light interference and produce different colours on the silver surface, depending on the thickness of the silver sulfide tarnish layer. When the light from the top and the bottom of the tarnish recombines, some of the colours are lost through interference. The colour that remains depends on the thickness of the tarnish layer. In the early stages of tarnishing, as the thickness grows from 10 to 100 nanometres (nm), the colour changes from yellow through red-brown to blue. For thicknesses greater than about 100 nm, the colour is black, the true colour of silver sulfide (Selwyn 2004). This is due to a phenomenon called “thin film interference.” As light hits the thin film of tarnish on the silver, it splits; some of it reflects off the top surface, and some of it reflects off the silver under the tarnish
