1970 Netherlands 1 gulden; this is a proof right? How do I value or grade it?

So I compared this to a 1969 non-proof, and the crest and head are not frosted, so I am assuming that means proof. I don't have another 1970 to compare it to for sure. So how do I value and grade this then? KM says $350.00 for proof, but they don't say if it is proof 70 or what it is for the value. Please assist. Thanks!

Most Wilhelmina coinage comes out frosted and gets worn through circulation, so this is no proof issue

How do i identify proof? I have quite a few that are less frosted and not as reflective. So is there a special die variation?

I have a proof set somewhere, if I can find them I will post pictures so you can see the difference.

Thank you!!! I have a ton of these coins (not all same date) I got them in a big lot a while back, and never messed with them really.

So here, I found 2 1968 coins, that are very apparently different!
One is frosted, one is not.

The second one the inside of shield is same color as rest of coin, the first the shield inside is frosted. So what does this mean? I assume it could not be just wear, as the face of the one is frosted too, and the other is not. The Cata entry says 1968 has no proofs. However How do I tell a proof from a regular one, especially if they are circulated. I mean I have quite a few of these, and so far 50% are frosted, and 50% are not. some with same dates.

Most dies begin their lives a little bit frosted. The delicate frosting soon wears off with use.

With some Canadian coins, there are "Cameo", "Heavy Cameo", and "Ultra Heavy Cameo", meaning different amounts of this frosting. The coveted Ultra Heavy Cameo is only seen on the first few coins struck by those dies (maybe an amount only in the single digits!) and look almost like proofs.

I also notice lots of variety in the frosting on Dutch coins, I suppose it's just random chance depending on how old the die was.

So this means that there are "Proof like" coins, made from business strikes? If this is so, then they must command a higher value than the normal business right?

I for example found 10 25 cents Netherlands with the same issue, 9 of them are frosted, and the rest are not. I have never seen this any where but the Netherlands. Weird for sure.

You grade proof coins the same way you grade any coin.
As for value frosted proofs must have the same texture of
Frost on both sides to get the full value of a proof coin.
And of course book values are not necessarily the price you
Will get for the coin unless you find someone who is willing
To pay full book price. Jim

The 1st coin is a standard unc coin and the 2nd coin is the proof version. Hope this helps to see the difference.

Notice the mirror-like field of the coin.

Dutch proof coins from the Juliana reign are pretty hard to find, so chances are very little some of them are mixed up with cirulation coins. Also, the Royal Dutch Mint produces high quality circulation coins in general, so it's not really that rare to find circulation coins in proof like condition (with a matte and mirror surface).
By the way, there actually isn't a mintmark or something similar to indicate a coin as a proof coin, so you can only tell by the way it looks whether the coin is proof or not.

if it came from circulation, it is most certainly not a proof.

I got them in a collection lot, The person I got them from had a lot of proof coins, and the frosting on a few of my Netherlands guldens are very proof like, and as for mirror finish, a few surely look mirror finish. I think maybe out of the lot of them I have, maybe 2 or 3 are going to be proof if I get them looked at.

Took that specific coin to 4 shops, 3 said proof, 1 said no. Got offered over $100.00 (not much more) by those 3 shops, In my opinion = proof. Refer to my newest thread with a coin that was only issued as proof, and the dilemma with identifying proof coins which are worn or dirty.

I have a follow-up question on this issue.
Lately I found quite allot very shiny 1,2,5 Euro-cents from Germany and I'm asking myself if they could be 'proof'?
Therefor: (1) Are there 'proof' 1,2,3 cents around? (2) Could somebody who has one post a picture, so I can compare that to mine?

Can you perhaps post a picture by yourself?

Quote: Palinka83I found quite allot

That is clue №1, there are not many proofs outside of sets and I don't think my local discounter get their change in proof coinrolls from which I get many such nice looking coins
They are simply straight from the mint to the roll to the cash register and the little coins don't get so scratched up in the minting process like the bigger ones so they stay nice and shiny but they are no proofs.

@ Lotus:
Here are some of them. To me they have at least some 'mirror-effect'.


@Idolenz:
'Allot' was exaggerated and fyi they're not from the discounter but from an organic-food dealer  

Guess eventually I just have to get one or two 'proof' coins to have example pieces at the house.

First off all, thank you for the pictures. Unfortunately they are not proofs. I've a couple of 1 eurocents from 2014 which are also minted in Germany and they have the exact shine like yours. I guess I thought at first sight they are proofs because of that shine, but believe me, most Mint houses produce such high-quality coins these days that it's possible to get almost the same shine as proofcoins have. But I believe proof eurocoins have frosted (or matte) details. The same counts for Switzerland, I went there last year and almost every 2012, 2011 or 2010 coin looked like a proofcoin, because of the frosted Liberty bust on the obverse and the mirror-like shine on the backround. I know it wasn't to find proofcoins inmy change every time I looked, so it was more easier to say that those are just a high-quality minted coins.
