    Thanks for the advice! Is it safe to use coin care on copper? I've only used ammonia on a couple morgan dollars in which the pvc was literally crusted onto the coins.

    I had an EAC guy recommend olive oil to me, however advice isn't always good advice, as I frequently learn. Fortunately I probably haven't done too much harm, as the nicest coin I have used it on is a 1909 vdb lincoln cent.

    Any advice on removing the olive oil from my coins that currently have it?

    Good luck on getting it off - the only thing I know that will remove it is a solvent. And copper does not like solvents :mad:

    Listen - in the old days they used to put everything under the sun on coins. They used oils, they used lacquers, they used fingernail polish etc etc. They always said - "it was to protect them". But have you ever stopped to think why it is that 80% or more of all older coins are considered problem coins today ?

    Well if you haven't put 2 and 2 together yet it's because of all the stupid things that collectors and dealers alike used to do to coins to protect them.

    With my dying breath I am going to say this - Leave Coins Alone ! They can't be improved and they can't be protected ( except by proper storage ).

    That's some good advice Doug! I've heard so many individuals recommend coin care and the blue ribbon, but if it is so foolproof, I suppose it would always be used, and you wouldn't see so many coins that have turned in their holders.

    After checking my lincoln cent it has turned from red to red-brown. Lesson learned :(

    Well, for those who haven't learned the lesson you did Zane let me say this. What do you suppose happens to any of these products after you put them on a coin to protect it ? Eventually the stuff drys up. And I don't care if it's Blue Ribbon, Coin Care, olive oil or 10W30 - eventually it is going to dry up. And when it does - that's when the problems show up. Note I said show up - the problem actually starts when you put the stuff on the coin. It just doesn't show up right away.

    Now this has turned into an interesting thread for me at least.

    As stated I don't go for cleaning coins but it does happen - that's reality.
    My Blue Ribbon coins still look quite fine.
    Should I slab them now so I can get the grade and the holder?

    AMEN Doug!! - Even the most "non harsh" treatment will show up after a few years. Trust me! I've tried, and even got a few coins slabbed by both NGC and PGCS after a quick acetone dip and a distilled water rinse.... Two years later the coins show the "drying effect" (even after being placed in interept shiled holders and boxes. Be warned! Unless full of verdigris or corrosion, don't mess with your coins.

    That's a choice that only you can make. But before you do, please for the sake of others who may own the coins later - think about it.
