Here is my research:

• Royal Hawaiian Mint records indicate that the obverse is dated 1990 with portrait of King Kalakaua and the text “Kalakaua I King of Hawaii”.
• The reverse is dated 1941 – 1991 with the island of Oahu and the Pearl Harbor Memorial.
• It is 10mm in diameter and struck in gold.  
• Records also indicate a very minuscule mintage of 24 specimens.
• As a background note, the Royal Hawaiian Mint struck gold in 17mm diameter (1/10 ounce) and 13mm (1/20 ounce).
• In 1991, only the 1/10 ounce gold (17mm) was struck (with a Liberty Head obverse with a Pearl Harbor designed reverse). 

The big question is why was a 10mm gold coin struck?

Here lies the answer:

• The 10mm dies (obverse and reverse)  had another purpose.
• It was used to counter-strike a number of 1991 US Silver Eagles!
• Records indicate that ten 1991 US Silver Eagles were counter-struck with the 10mm dies. 
• Images are provided to as visual evidence and confirmation (click the image to expand the size).

Here is a listing of the RHM dies that were used as counter-stamps. The bolded entries are coins using the original die(s).  

1.   1991 Pearl Harbor Dala 10 mm dies (24 – 10 mm gold coins):

• 10 – 1991 US Silver Eagles

2.    1981 Liliokalani IKI 13 mm dies (55 – 13 mm gold coins):

• 38 – 1982 Kala Dala

3.   1989 King Kalakaua 13 mm dies (100 – 13 mm 1989 Kalakaua HSNA gold coins)

• 3 – 1989 10th Birthday Commemorative

4.   1990 Liliokalani 13 mm Obverse die/ Grand Opening 6-9-90 13 mm reverse die (Combined – None)

(Obverse die only was used on 25 – 1990 Liliuokalani HSNA Gold 13mm)

5.   1990 Liliokalani 13 mm Obverse die/ First Day Issue 3-9-91 13 mm reverse die (Combine – None)

(Obverse die only was used on 25 – 1990 Liliuokalani HSNA Gold 13mm)

• 340 – 1991 Kaiulani Silver Dala

6.   Aloha Money 10 mm dies (None):

• 515 (sets of 4 coins) – 1993 US quarter, dime, nickel and penny

In summary, the 1991 Pearl Harbor Dala 10 mm dies are the most elusive as a coin and as a counter-stamp.

I’ve been gauging the market on Royal Hawaiian Mint (RHM) products at a well known online auction site. Several  of the counter-stamp items  are being offered over the $1000 threshold.  It seems that the sellers perceive these are rare products.  Let’s see what the market can bear for price?

However, let the buyer beware. Do your research!

Below is my research on the 1991 Hawaii Princess Dala (aka Princess Kaiulani Heir Apparent).  Mintage is 1,100. Only 340 were counter-stamped.  Current catalog value for counter-stamp variety is $85.00 (eighty-five dollars, not a typo). This is approximately a 1176.47%  price difference for a December 2012 catalog value and the current auction price listing.  Let me spell it out….P R I C E  <space> G O U G I N G! (I’m also guilty with auction items that are hard to replace after its sold…)

Sorry, the sources are kept confidential for my research/writing.

Using the Fuld rarity scale. The series is a R-3 (501- 2000) specimens. The counter-stamp variety is an R-4 (201 -500) specimens.

Unless you have money to burn…the $1000 for an R-4 specimen is too high for my budget.

Below are images of other RHM counter-stamp products.

New topic …. (Just a note on my part)

There is a R-9 (2 – 4 specimens) Platinum Puela pattern being offered  slightly above $4,000  at this online website. My research indicates his mark-up is $2,870  after owning the piece for little over 5 years:

sources ….   2013 want price and 2008 purchase price (note the seller choice of ID match).

I’ve located, purchased,  and added a 2M-200 to my collection.

It’s a 1989 Unofficial HSNA medal, 13mm,  1/20 ounce gold, 0.999 finess. Struck by the Royal Hawaiian Mint with a mintage of a mere 100 specimens.

I keep admiring  a Pantheon Saloon token being offered by a dealer and could no longer resist. I had to make it part of  my collection.

I compared this specimen with images of others that I could find online. I finally decided to purchase it after comparing it with a NGC MS63 specimen. I believe this one will grade higher if I submitted to NGC. The only issue I may have is the surface (which maybe taken care of by NCS).

The  strike is incredibly bold and the  details look freshly minted. No trace of wear. The selling point for me was the boldness of the small text “C.A. Klinker & Co. S.F”. Where SF is San Francisco.

Here is a link to an image of the Pantheon Saloon in the late 1880’s.  

As for the token’s year, most online references (at auction websites) indicate 1895 . As I have investigated, it maybe as earlier 1881 as this October 1881 newspaper clipping indicates.  Jim Dodd’s Pantheon Saloon licences (retail spirit and billiards) was to expire in the month of November 1881.

Here is the obverse view…I’m researching this item…
