This option is best for the high grade seeker who demands perfection. It is intended for those who look beyond the standard mint packaging to find coins that have been professionally graded and encapsulated.

Buyers frequently choose this when they want guaranteed visual perfection.
Professional grading provides a level of security that raw sets lack.
The slabbed coins are easier to display but harder to store in bulk.

To me, this set is more about the joy of the hobby than the potential for massive financial gains. It is a clean, well-preserved window into a specific moment in minting history.

4. 1987 S U.S. Proof Set in Original Government Packaging
The most common complaint about this set is that it is often confused with the 1988 version, yet it remains vital for those finishing their late eighties collection. It lacks the specific cultural context of the 1988 year, but its quality is identical.
I think it is a mistake to ignore this year if you are aiming for a complete decade run. You get the same high-quality minting standards without the premium associated with more famous years.
The biggest limitation noted by collectors is the lack of a commemorative coin.
It remains a secondary target for those who have already finished their 1988 requirements.
Market interest is steady but rarely experiences significant spikes.

8. 1988 S Prestige Proof Set Collection US Mint
This set is best for the serious collector who wants the highest numismatic value. It is the premier choice because it includes the commemorative silver dollar alongside the standard coins.

The inclusion of a silver dollar makes this a top-tier choice for investors.
Buyers note that the presentation box is significantly more impressive than standard sets.
It is the most frequently recommended set for those looking for long-term value.

Choosing Between Them
The 1988 S Prestige Proof Set is my top pick because it includes the commemorative silver dollar, which offers significantly more intrinsic metal value than the standard proof sets. For those seeking a standard collector baseline, the 1988 S US Mint Proof Set is sufficient, while the high grade seekers should look toward the PR-67 version. Collectors focused on the early nineties will find the 1990 and 1991 sets quite appealing, whereas those finishing their late eighties run or watching their budget should opt for the 1987 or 1989 sets respectively.
The 1997 set rounds out the selection for those interested in modern proof aesthetics, though you should remember that coin market prices fluctuate based on silver spot prices and overall collector demand. Regardless of which set you choose, ensure you keep the original packaging intact, as it is crucial for maintaining the future resale potential of your coins.
