Finding PCI Slabbed Coins in the Wild: A Cherry Picker’s Guide

The Thrill of the Hunt: Discovering PCI Slabs

You don’t always need a dealer to find this. Here is what to look for when searching through circulation or bulk lots.

Roll hunting and cherry picking have long been the backbone of numismatic collecting for those who enjoy the thrill of discovery. While many collectors focus on certified coins from major grading services, there’s a fascinating subset of vintage slabs that can still be found in the wild if you know what to look for. One such treasure trove comes from PCI (Pacific Coast International), a now-defunct grading service whose holders have become collectible in their own right.

PCI Slabs: A Brief History

PCI slabs represent an interesting chapter in coin grading history. These holders were originally designed, produced, and used by Hallmark, a legitimate grading firm formed by Lee Bellisario and partners including QDB. Unfortunately, Hallmark failed to gain marketplace support and quickly went out of business. The PCI brand later acquired these holders and continued using them, creating a unique collecting opportunity for today’s enthusiasts.

What Makes PCI Slabs Special?

Several factors make PCI slabs particularly interesting for collectors:

• The distinctive toning that often develops inside these holders
• The “100% White” designation that PCI boldly placed on some coins
• The relative scarcity compared to modern slabs
• The historical significance as artifacts from a transitional period in coin grading

Identifying PCI Slabs in Circulation

When searching through bulk lots, estate sales, or even circulation, here’s what to look for:

Visual Markers

PCI slabs have distinctive characteristics that set them apart from other vintage holders:

• Clear, thick plastic construction
• Distinctive label design with PCI branding
• Often feature colorful toning on the coins inside
• May include the “100% White” designation on some coins

Common Dates and Types

While you might find any denomination, some of the most commonly encountered PCI slabs include:

• Morgan Dollars
• Franklin Half Dollars
• Various type coins

The Toning Phenomenon

One of the most fascinating aspects of PCI slabs is the toning that develops inside them. Many collectors have observed that these holders seem to produce particularly attractive toning patterns. Some have even noted that the toning can progress from attractive to “terminal” if left unchecked for too long.

Why Does Toning Occur?

The exact cause of the toning in PCI holders remains somewhat mysterious. It’s unlikely to be the inserts or the slab itself, as Hallmark slabs (which used the same holders) typically didn’t produce the same dramatic toning effects. This suggests there may have been something unique about how PCI handled or stored their coins.

Value Considerations

When evaluating PCI slabs, consider these factors:

Grade and Eye Appeal

The coin’s grade and overall eye appeal remain important, but the holder itself adds a premium. A nicely toned PCI slab can command significantly more than the same coin in a modern holder.

Holder Condition

Interestingly, many PCI slabs remain in excellent condition despite their age. This could be due to the slabs being harder/more scratch resistant, or simply because they were handled less often being from a “lesser” brand.

Market Demand

There’s growing interest in PCI slabs among collectors who appreciate their historical significance and the unique toning they often contain. Some collectors are even building complete type sets in PCI holders.

Where to Find PCI Slabs

Several venues remain good hunting grounds for PCI slabs:

Local Coin Shows

Events like the PNNA show mentioned by collectors can be excellent places to find PCI slabs. Dealers often have boxes of raw coins or older slabs that haven’t been thoroughly searched.

Estate Sales and Auctions

Older collections often contain vintage slabs that haven’t been cracked out and resubmitted. These can be goldmines for cherry pickers.

Online Marketplaces

While more competitive, online venues still occasionally list PCI slabs, particularly in bulk lots or unsorted collections.

Preservation and Care

If you’re lucky enough to find PCI slabs, consider these preservation tips:

Leave Them As-Is

Many collectors prefer to keep coins in their original PCI holders, both for historical authenticity and because the toning is part of the coin’s story.

Monitor Toning

If you do keep coins in PCI holders, monitor the toning progression. Some collectors have noted that toning can continue to darken over time.

Resubmission Considerations

Some collectors consider cracking out PCI coins and resubmitting to modern services. However, there’s always the risk of receiving a “Questionable Color” (QC) designation, particularly for coins with significant toning.

Building a PCI Collection

Several collectors have started building themed collections around PCI slabs:

Type Sets

Creating a type set in PCI holders has become a popular project, with collectors seeking coins that “appeal to them and accurately graded” while appreciating the colorful toning from the old holders.

Denomination Runs

Some collectors focus on completing runs of specific denominations, like Morgan Dollars or Franklin Half Dollars, all in PCI slabs.

The Enduring Appeal of PCI Slabs

PCI slabs represent a unique opportunity for collectors who enjoy the hunt as much as the acquisition. These vintage holders offer a window into the early days of third-party grading while often containing beautifully toned coins that tell their own story. Whether you’re searching through bulk lots at a local show or carefully examining estate sale offerings, knowing what to look for can lead to some truly special finds. The combination of historical significance, aesthetic appeal, and relative scarcity makes PCI slabs a fascinating niche for today’s cherry pickers and roll hunters.
