I'm 99% certain you're trolling. I also highly doubt that all that was done was a 10 minute soak in olive oil and MS70. Olive oil is not reactive enough to change the surfaces in 10 minutes. You'd have needed to do some serious rubbing with MS70 to get all the color off. There are ways to lessen or remove those dark areas without harming the originality of the coin.

Always found Iceland coins interesting. Their designs are very much what I envision Iceland life like when they minted them, harsh, rugged, barren, and to the point. Too bad so few people collect them. Here are a few unusual ones I've picked up over the years. 1957 Eyrir in PR66BN. The only example graded at either PCGS/NGC. 1963 5 Aurar in PR65 BN. Only 5 examples graded by PCGS/NGC with this the finest by a point. 1954 25 Aurar in PR66 Cameo. Only 3 examples graded at PCGS/NGC with this being the only Cameo. 1962 2 Kronur in PR66. Nine total examples graded by PCGS/NGC. Usually found in impaired condition. Tied with 2 others for top pop.

For the most part these coins are available in gem condition and fairly cheap. I looked through my records and show I have sold 60+ of these that were graded over the past 10 years or so. Even the "scarce 1933" are available. I was offered a deal with several hundred of these in UNC. I second Karl Stephens as a dealer to trust with his grading. Del Parker is a big Irish coin dealer in the US. He has some nice stuff.

Their price guide is very wrong. This is a super common coin even in gem. It's a hoard coin. I'd guess an MS67 around $350-$450.

Best guess:

Post some pictures. Let's see this 50+ year natural color on those MS67 gems.

In a perfect world, sure, but we don't know anything about the submission history of this coin. Maybe it was a standard submission listed as MS the first time. Maybe the second submission listed is as SP and included numerous outside opinions from experts in the field that the coin is not a regular business strike? I own two coins that were graded a minimum of twice at both NGC & PCGS and they came back MS every time. No proofs were ever minted. Today they both reside in SP holders after I got an expert to state they they were not normal business strikes. And I dare anyone to say they are not special. Maybe the first time the dime was graded every grader except one said SP and NGC erred on the side of caution? Maybe the second time they decided to go with the majority of graders? Maybe this dime was first graded when NGC stuck to the MS or PF designations? I don't know this for a fact, but I sure saw a lot of PCGS SP coins before NGC, so maybe NGC was slow to use SP designations? FYI, I'm not defending the SP status of this coin in particular.

In most instances it is called “specimen” because the coins looks like something unusual or special was done, but there is no reliable documentation. It’s a way of saying the coin is “different but we don’t know what it was supposed to be.”

Since when does there need to be documentation? There is a long history of mints keeping "special looking" examples of coins.The term Specimen does not indicate a proof striking. It's used today to denote a coin that has a special appearance and likely special handling. If this coin looks nothing like a regular 1900-S, then the SP designation may very well be warranted. And I own quite a few undeniable proof coins from various countries. Only problem is that according to the mints, they didn't make any proofs. Are they suddenly not proofs? I've also owned mint state examples of proof only issues.
