1827 is a tough and long year. It has 49 die marriages, the most of any year. They include #6 R-5's. One R-6-, and one R-6+ And even an R-8! There are also 11 R-4's [including + and -] I only have 7 of the R-4's, and one R-5.
Does look like PVC on AceKing's 1836. Speaking of bust halves that start an obsession...here's my first one.
strangely, I just noticed that this is not in my computer, and can't find the piece anywhere. I do know I recently up graded it: But, I have no idea where the other one is.
I posted that one on NGC once and made the comment that it had PVC. Dave (Mailboxaddict) noted that it MAY be wax from a leather pouch it MAY have been kept in. I did try giving it an acetone dip, but it's still there. I've had the coin since the late 80s and it doesn't appear to have any deterioration in that time.
