Do some PCGS green inserts turn blue?

braddick

I came upon this coin and haven't seen a blue insert with the older style font from PCGS before.
Then I recall somewhere- probably here- that the blue label was really green that changed over time.

I can't find that thread or anything related to my speculation, so wanted to ask here.

"Occasional shades of blue or yellow."

Interesting! Thanks for bringing that info. to light.

Cool thread. Here’s one I had, now sold:

Your 1899 dollar you used to own looks better than MS64... I wonder what it is wrapped up in now.

There was a coin shop in downtown Baltimore near where I worked. The shop had a window display with a few inexpensive coins including a couple of older PCGS slabs. The window was in direct sunlight and the labels over time turned yellow so I assume that it was a result prolonged exposure to direct sunlight.

Art McBride bought it from me at a local show some 5+ years ago. Unless it was cracked out & submitted, the old holder in the pic still shows “active”.

I have seen them turn blue, yellow, tan and even near-white.

I had one turn completely yellow after leaving it on a window sill. It must have been there for perhaps 9-10 mos. This was back in 2005 I believe.

Here are some of various colors. The MS63 is probably the closest to the should be green.
I positioned them on the screen and took a screen shot.

The green label contained a mixture of yellow and blue dye coloring . When the yellow dye lost its integrity, the label turned to its remaining blue color .

When the blue dye lost its integrity the label turned to its remaining yellow color. When both the blue and yellow dye lost their integrity the label turned white. I cannot fully explain how the label turned to a tan color.

Exposure to sunlight has a bleaching effect on dyes. You can see it in fabrics and automobile paint that have faded from long term exposure to the direct rays of the sun.

That is why I fear buying slabbed coins in an outdoor flea market. They sit baking in a hot sun all day ruining the coins not just the slabs as well as the US Mint packaging.

I don’t think any of mine are blue, but I have varying tones of green, plus the camera can change it slightly.

Do you frequently encounter slabbed coins at an outdoor flea market? I cant say that I recall seeing that.

Rarely, more often I see post 1968 proof sets sitting in the sun. But not as often as before.
