Mint Error? 1968 Lincoln Memorial Penny

The no mint mark thing happens on all Philly cents. That is normal.

The eyes are playing tricks on you. When you see something on a coin, then the mint figures out something when it is nothing. This happens a lot on new collectors. After a few thousands of cent your realize if is nothing like any shape of any device from the mint process and then see if could not be a hubbing issue, mint mark issue, just just something you notice on a coin. Damage can make material from the field raise in various directions. Just a normal coin with some damage.

Just keep searching. You will find something if you have a good loop and keen eye for spoting what to look for.

You can always go buy some from the bank. I have had good luck with roll hunting and so have many others.

Thanks everyone. I found some more old coins. Here is one of them that I have on ebay. I have nothing to lose. I explained about it at the auction.

I just see a die chip on the "T". Common. A Cud is a breaking off of the outside edge of a die that shows on the rim. These are desirable to collectors. A chip is common.

Anyone ever heard of a 68 no mint mark doubled die date Liberty and the Trust

Here is a machine doubled example on the date.

These were very common on that year.

Troy Meyer1, without an image I'd only be guessing. Maybe the same OP example released back into circulation. Since 2014 I see a few added comments saying they have the same or something similar, even an unrelated possible doubled die date, but In all honesty I need something to examine prior to any attempt at confirmation. Thanks, Doug.
