Have you ever?

Have you ever gone through your collection and find a coin in it that was mislabeled or your forgot you had it. I just had this happen. I am in the process of re-organizing my collection and I was searching in a small box and I found a Eastern Caribbean coin. It was labeled as 10 Cents 1965. But upon further inspection it turns out it is a Eastern Caribbean 50 cent coin 1965. With a mintage of only 100,000 and I didn't even know I had it. The only problem is that the obverse has some bad scratches but it still made my day. I would like to read about anybody else's experience with this.

Happens all the time with stamps, not so much with coins.

In my books I'm always finding a wrongly identified stamp, since watermarks are hard to discern, as well as the different sized preforations.

Mostly they are recorded thanks to Numista!
But this reminds me that I have couple of Princely State coins that I couldn't find any details and left them unlabeled.

I agree with you on the stamps one Kenny, I used to have a pretty extensive Japanese collection and the ones from the 1920s and 1930s were such a complex series to get, so many different perfs, watermarks, etc.  I used to live the chrysanthemum series from the late 1800s to the early 1900s.

If you need help with Japanese stamp identifying, I can help.

I guess you could say I'm an expert in both Asian coins and stamps. Look out for large-small dies, no watermark, thick wave watermark, thin wave watermark... that's pretty much all you need to know when working with 1920's-30's Japanese stamps. Sorry my ancestors had to make it hard for you.

Going back to coins, Roman, Indian, and Tibetian coins are extremely hard to identify. I say this because they are sitting on my desk and I don't even bother to look them up.

Yes, I looked at my Swiss coincollection yesterday and than I saw I had a pretty rare 5 Rappen from 1965 It has only a mintage of 1,430,000.

Glad I read this post...I went through my collection last night after doing so, comparing it with what I have registered on Numista and I was really excited to find out that I had mislabeled a Rhodesian 20¢ as 1975 rather than the 1977 that it was.  Closed out that series, without buying a duplicate by mistake!

I think it can be a sign of growing in knowledge and experience to find errors in your labelling or work from earlier in your collecting life

I found out I had a Manchukuo 5 fen/sen coin that I got when I was very young...

I bought a lot of coins in Germany... I pulled out a particular piece that looked of gold ( my father said it was impossible...) and about 2 months after, I searched it up on Numista and...

In the same lot... I didn't realize it's scarcity until late 2012

And that gold coin is a real one???  

I spot an overlooked mintmark or variety once or twice per year.

I am more guilty of misplacing coins that I've already cataloged.  I know I have it... I just can't find it!

That's my biggest problem too!

Yeah, happens me all the time as well. I really have to sort out my penny's and half penny's from the UK by letter!

Yup! You can't really fake gold. The weight was exact.

I don't know, I need to sort them out first before I can tell that to you!  

I don't know what you mean, like H for Heaton or KN for King's Norton?

I've got a big box of half pennies and pennies, but I've always collected them by year, I didn't know that they sometimes have different mintletters on them. So I've never looked at them at that way. That's why I have to sort them out and to look if I can find any mintletters on them. And yes, than I look for mintmarks as an H or KN.
