White film on a high grade coin? What is it?

Hello all,

I have a question for all the experts--and there are plenty of you out there (seriously, no sarcasm intended) I have a 1969 PR70 CAM and it has a white film all over the smooth, shiny part of the obverse. I don't want to quibble over it being graded too high. I am a platinum member of PCGS and have most of my coins graded there--sometimes I have to go to NGC, who will at times grade a coin that PCGS wouldn't (such as a coin with a rim nick). Anyway, back to the point, the coin truly does appear perfect in every way. I can't find even the tiniest of hairline scratches--perfect except for this white film. I've already checked and it is not on the slab itself. What would cause a coin to have a white film on it? It looks like you could take a light, soft cotton cloth and gently rub it and it would be gone, but I don't know. Has anyone seen this before and if so what is it. Also, why would a grading company--even a third rate grading company give the coin a 70 if it no longer looked to be a proof with the film all over it? I look forward to any answers.

    69 proof...sounds like haze, or sometimes can be little spots like milk spots...usually due to way the planchets were handled..if it covers the entire obv sounds like planchet wash...i know 50s 60s proof coins they used ivory liquid n warm water...but they stopped it mid 60s i thought.

    That one sounds like a definite grade guarantee candidate. Since you're already a Collector's Club member, you're probably familiar with submissions. Just do a regrade submission on the coin and write "grade guarantee" somewhere prominently on the form.

  • For pontiacinf,

    Does this milky film effect the grade of the coin? IF it appears to be nearly flawless, would it be graded so with this milky substance?

  • Hey Russ,

    Do you believe the white film on the obverse would lower the grade of the coin? It looks like you could just rinse it in good old H20 and very gently dry it with a soft cotton cloth in order to get the film off. However, it also speaks of something very interesting. If they used ivory soap to clean the coins back then and this coin is covered in this thin white film, it would give testimony to the fact that the coin has hardly ever been touched, otherwise the film would get rubbed off--but there it is. This could help validate why the coin was a PR70, seeing evidence of little to barely ever being touched. What do you think?

    Of course it does. There's no way it should grade 70 with white film on it. Like I said, send it to PCGS for grade guarantee.

    I once tried to dip milky haze off of a proof Washington...didn't even subdue it. I also think the haze had been expanding throughout the years, so I sold the coin to a dealer.
