An Introduction to Coin Grading and Preservation - Saturday, Nov 23, 2019

The RCNA is sponsoring one of its popular, one-day workshop events titled "An Introduction to Coin Grading and Preservation". It features two very qualified instructors: Robert Forbes and Susan Maltby.

Date: Saturday, November 23

Time: 9:00 am - 4:15 pm

Location: Humber College, 205 Humber College Blvd., Toronto, Ontario (located in Northwest Toronto) (Community Room)


The Coin Grading and Preservation course, sponsored by the RCNA, will featuring instruction by numismatic experts Robert Rorbes and Susan Maltby.

Following the introductory course, this course delves much deeper into the technical aspects of coin grading, counterfeit detection, fakes and alterations, authentication, as well as coin & paper money preservation. Although not a pre-requisite, participants would benefit from having taken the previous course. This course has the goal of educating collectors about the technical side of grading Canadian coins.

The two highly qualified instructors will supplement their discussion with slides, demonstrations, hand-outs and displays of relevant numismatic material.

The class size is deliberately kept small, facilitating the students to have an opportunity to interface, one-on-one, with instructors to either understand the material presented more clearly or to deal with other issues of interest to the student in the instructors' areas of expertise. 

Henry Nienhuis, RCNA President, will act as the Moderator for the workshop.

Each participant will receive a special RCNA "Certificate of Participation" at the conclusion of the course.

The day long course will include 45 minutes for lunch where participants can dine in the Humber College restaurant (the cost for lunch is the responsibility of each individual). Morning and afternoon coffee breaks are also scheduled with complimentary coffee and tea being available.

The Morning session explores technical aspects of grading Canadian coins including market grading and the use of professional grading services.

This session will focus on the practical aspects of grading Canadian decimal coinage.  The material presented covers the three fundamentals of accurate and consistent grading : knowledge, technique and objectivity.  Important grading tips and methods used by experienced graders will be explained including "market grading" and the use of various coin grading services.  A detailed discussion of the fine points that distinguish one grade from another is also included, as well as a close-up look at "coin problems", specifically those coins that are cleaned or altered.

This course is intended for students who know the basics of grading coins, have some grading experience, and recognize those areas where they lack grading skills.

All students are encouraged to bring examples of coins for class discussion.  This course will help students resolve the confusion that sometimes accompanies grading coins.  

Coin & Paper Money Preservation (1:00 - 4:00 p.m.)

Instructor: Susan Maltby, Toronto, Ontario

One of the most important aspects for the preservation of coins, tokens and paper money is providing proper handling and providing proper storage. Collections can deteriorate with time if not stored correctly. Find out what you can do to ensure minimal reduction in value of valuable numismatic material.

This advanced course offers the collector an opportunity to learn, in a practical “hands on” manner, more about the proper care and conservation of numismatic collections (i.e. coins, tokens, medals and paper notes).

Topics discussed will include:
- agents of deterioration
- environmental requirements for numismatic collections
- environmental monitoring techniques
- establishing a controlled environment
- storage
- holders
- cleaning, care and handling of numismatic material

Components of a great coin/bill holder, how to choose a good holder, materials and holders to avoid, environmental requirements for different kinds of material (i.e. different metals, paper, “exotic materials) will be addressed, as well as offering tips on good care and handling.

One of the demonstrations that will be included, because of its importance to determining the content of storage materials, is the Beilstein Test, used to determine whether a plastic contains PVC or polyvinyl-dene chloride...and will explain which is safe, which is not and why.

Participants are urged to bring along problem pieces for examination and discussion.

Susan Maltby is a columnist and professional conservation consultant.   She has given seminars and presentations on numismatic conservation to a variety of numismatic groups during the past few years. Susan was a member of the staff of the Canadian Conservation Institute in Ottawa prior to starting her own conservation consulting firm.
