Very interesting thread. I've already stated my views regarding how various TPGs operate in at least one other thread, so there's no need for me to resurrect it again here. However, in answer to the original question of where to send coins for variety/error notations: if the coin is Canadian, I would recommend sending to Louis at CCCS. They have been very good at commenting errors and varieties provided (a) customers point it out in their submission, and (b) the variety/error is visible. Since I'm a heavy variety & error collector (among other things), it's important to me that the notations are made on the certification -- especially for insurance purposes. I've been very pleased with CCCS's grading standards so far, which I would describe as being comparable to ICCS, as is their pricing. I find CCCS's customer service and value-added benefits very attractive as well, in addition to getting the option to hard-slab if I so choose. Another good
TPG to consider for error/variety recognition is NGC; but if I had to choose between CCCS and NGC, I find CCCS to be superior at certifying Canadian errors and varieties. Hope this helps.
