I discovered an unusual variety of the 1999 state quarters while checking my collection. Could it be a flip over error? How do I properly attribute it?

Hey everyone!

I was recently going through my state quarter collection when I stumbled upon what seems to be a rather unusual 1999 quarter. At first glance, it looks just like the usual Delaware state quarter, but upon closer inspection, I’m questioning if it might actually be a flip over error. The reverse side is facing the right way, but it seems the obverse has some strange alignment issues. The coin is in pretty decent shape, rated around MS-63, with only a few minor scratches. Have any of you come across something like this?

I’ve done a bit of research and found some documentation on flip over errors, but most examples are from years earlier than 1999. I’m curious about how to properly attribute this find. Should I be looking at specific markers to confirm it? I’d love to hear your thoughts on how these types of errors are cataloged and what the potential value could be.

What are your experiences with 1999 state quarters? Have you ever discovered something like this? Any tips on thorough attribution would be really appreciated!

That’s really interesting! Flip over errors can be quite rare, so it’s exciting that you’ve possibly found one. Based on what you’ve described, it sounds like it could indeed be a rare variety. I came across a similar situation last year with a 2000 state quarter that exhibited some odd orientation issues. In terms of attribution, you should consider the following markers:

  • Overall weight compared to a regular quarter.
  • Any noticeable die cracks or other errors around the rim.
  • How the alignment differs when the coin is flipped.
Additionally, you might want to compare it against resources like PCGS or NGC for reference images of known flip errors. Keep us updated!

Thanks for the comprehensive feedback, @CoinExplorer99! I really appreciate the tips on the markers to check for. I hadn’t thought about the weight comparison. I’ll start looking into resources on PCGS for more references!
If it turns out to be an error, how much do you think it could be worth?

Great find! The value really depends on the demand for error coins, but a good flip over error could fetch anywhere from $50 to over $200 if graded well. Don’t forget to keep everything documented with photos and any grading notes you find along the way. You might also want to consider submitting it for grading to authenticate its rarity!

I’ve collected state quarters for years and I can say that errors like these do pop up relatively rarely. For state quarters, a flip over error can sometimes be less documented as compared to earlier coins. The best practice I followed was to build a relationship with other local collectors or a coin club for insights. They often have first-hand experience about rarer varieties!
Have you checked on forums like Collectors Universe? They can sometimes have specific discussions that might help you narrow it down!

Thanks, @CollectorDave! I haven’t explored Collectors Universe yet, but I’ll definitely check it out! It would be great to get insights from local collectors as well. Do you attend any coin shows? I hear they can be really beneficial.

Yes, I try to hit a few shows a year! They can be fantastic for networking and sometimes you can find dealers willing to give you the inside scoop on errors. Plus, seeing coins in hand beats pictures any day! Just remember to bring some of your own coins to trade or get opinions on. You never know what treasures you might come across.

That sounds like an awesome discovery! I love the idea of flip over errors, and finding one from a 1999 quarter would be pretty sweet.
Coin shows are definitely worth it! I once bought an entire state quarter set for just $20 because it was in a bag with other coins!
Keep us updated on your findings, and good luck with the attribution!

Coin errors can be a fascinating topic! You might consider using a microscope if you have one access to closely examine the coin for anything that isn’t visible to the naked eye. Sometimes, the tiniest details make a big difference in attribution!

Great tip, @NumismatistJoe! I don’t currently have access to a microscope, but I’ll see if I can borrow one from a friend or local library. It’s a good idea to get a closer look at those minute details. Have you ever found a flip over error yourself?

Yes, I found one a few years back! It was a 1998 quarter that had an obverse die rotation. I didn’t even know what it was at first until a fellow collector pointed it out at a club meeting. I had it graded and it ended up being valued at around $150! Keep your hopes high, @CoinEnthusiast87 - you never know what your coin might be worth!
