PCGS Certifies Canadian Cornerstone Collection

(Santa Ana, California) – Professional Coin Grading Service ( has added the Canadian Cornerstone Collection to its long list of historic collections graded. Submitted by Canadian dealer Sandy Campbell, the collection of proof and specimen coins dated from 1870-1953 features a wide range of unique and finest known pieces. Campbell’s company Proof Positive Coins Ltd. will be offering the coins for sale later this year.

The 255-coin collection, which took over 50 years to assemble, features 20 coins that are unique or not found anywhere in the public domain. Many other pieces are one of only two or three known. Aptly named the “Cornerstone” Collection as a cornerstone for Canadian numismatics it is anticipated to become a focal point for great collections. Sandy Campbell began acquiring items for the collection and submitting them to PCGS 30 years ago. “There is only one grading company when it comes to rare Canadian coins,” remarked Campbell as he reflected on his tenure submitting coins for authentication, grading and encapsulation for the Cornerstone Collection.

“PCGS is proud to have certified this collection,” stated Brett Charville, President of PCGS, “It represents a culmination of the last three decades of grading Canadian coins.”

The first major highlight of the Cornerstone Collection is the only available 1936 specimen dot set. This set contains a gem example of the 1936 1c Dot, graded PCGS SP65RB once featured as lot #1 in the Pittman Sale as his favorite coin. The set is “The Holy Grail” of Canadian Coins containing the finest known 1936 five cent through dollar: 1936 5c PCGS SP67+, 1936 10c Dot PCGS SP68, 1936 25c Dot PCGS SP68, 1936 50c PCGS SP68, 1936 S$1 PCGS SP67+. Dot coinage is popular among Canadian collectors as the market has been penetrated with ads to purchase these rarities for more than 80 years. Numismatic folklore became reality with the 1997 Pittman sale where it was placed into the market for the first time in more than 50 years.
