    And that...the condition of the Matte Surface is the reason for a lower grade on these coins than one might expect.

    Of course I have to wonder, Breen called them 70's, when did he write that? Is it possible they WEREN'T spotted when he saw them? Remember he's been dead for nearly 30 years now.

    I found this post on another forum and share it with you, as it pertains to these coins in question.

    Some members might have seen the recent announcements concerning a set of Daniel Boon 1837 Commemorative P-D-S proofs. Published information can be viewed here:

    https://coinweek.com/auctions-news/...ly-unique-matte-proof-1937-boone-half-dollar/

    The coins are definitely interesting and possibly unique, but unfortunately parts of the published description are wrong or misleading.

    First – the coins were struck on one of the Philadelphia Mint’s hydraulic medal presses. It appears the same obverse die was paired with a fresh reverse for Philadelphia, Denver and San Francisco.

    Second – the dies were normal production dies but unused.

    Third – the coins were struck once, not twice. There was no need to double strike since the medal press could easily bring up all the die detail with one “squeeze.”

    Fourth – after striking, the coins were sandblasted to create the micro-sparkling surface typical of mineral abrasive.

    Fifth – following sandblasting, the pieces were antiqued in a manner similar to silver medals. This produced the shading and enhanced sense of depth evident in the coins.

    Sixth – the coins were NOT some kind of secret off-the-books production, nor were they sold to influential collectors. The sandblast & antiqued coins were normal approval pieces made by John Sinnock for review by the Mint Director and Secretary of the Treasury. They were intended to show the commemorative design at its artistic best, and in a medallic presentation consistent with the desire of professional artists. These were normal test/trial pieces which do not appear on production records because they were not made for distribution or sale. (They would probably be mentioned in Engraving Department records, but those are almost all missing.)

    Seventh – similar antiquated sandblast proof pieces were made of all commemoratives during Sinnock’s tenure, and analogous pieces were struck during the terms of Charles Barber (except Columbian and Isabella) and George Morgan (1921 and 1922 Peace dollar proofs and antiqued pieces). These proofs and many others came from Sinnock’s estate after his death and have been floating from one collection to another since.

    The exaggerations, misleading, false and outdated information promoted by some is very discouraging. When will this hobby, or what little remains of it, decide that basic truth and honesty are much more exciting than tall tales

    Are these your opinion? Sounds like something Roger Burdette would have posted on CU but he is banned.

    I found it on the NGC site. Thanks for posting.

    @Insider See you found the post on NGC. Sorry for delay in replying, the time difference between you and here in Spain sometimes makes things a little difficult. Just thought it was an interesting take on the subject
