Official Texas Bullion Program – ACM Mint Mark Variety
Overview
The 1987 State of Texas 1 oz Silver Round (ACM) is part of the Texas-themed bullion series marketed under the Official Texas Bullion program. This issue represents the ACM mint-marked production run, documented across both 1986 and 1987, and associated with American Custom Minting within the broader Colonial Coins distribution framework.
The design follows the standard State of Texas format, featuring the Alamo and independence-era symbolism on the obverse and the Great Seal of Texas on the reverse, with the seal’s orientation intentionally reversed across the two sides of the round.
How to Identify This Round
The 1987 ACM variety is identified by the “ACM” mint mark below the date and a distinct set of measurable die characteristics. There is a star on either side of the date.
The Alamo façade displays five total windows, consisting of three upper windows across the front and one window on each side section. The structure shows a coarse, uneven stone texture with limited fine architectural detail.
The inscription “REMEMBER THE ALAMO – GOLIAD” is positioned above the Alamo, rendered in a raised format with rounded, often weakly defined letters.
The Six Flags are generally well defined. The Spanish flag (center left) shows crowned elements with smooth, minimally defined crown lines. The Mexican flag (lower left) lacks clear interior detail. The American flag (lower right) displays stars represented as small raised dots.
In the lower design, the cannon barrel is smooth with no visible contour lines, the bridge lacks defined support structure or cross-bracing, and the river below appears as a smooth field with faint, shallow engraving lines.
The inscription “TEXAS ONE AND INDIVISIBLE” below the design is clearly struck and easily legible.
Unique to the ACM Reverse Die: The reverse features a symmetrical decorative arrangement with eight acorns and four olives.
When these characteristics are observed together with the ACM mint mark, the round can be confidently attributed to the American Custom Minting production group within the State of Texas series.
Historical Context
The 1987 State of Texas silver round was issued during the rapid expansion of investor-focused precious metal products following the 1986 launch of the United States Mint’s modern bullion program, a period that introduced standardized gold and silver denominations and favorable tax treatment that increased demand for bullion ownership. Within this environment, Texas-themed rounds adopted a consistent one-ounce silver format while incorporating historical imagery derived from the State Seal of Texas, reflecting a coordinated effort to align regional identity and Texas history with the emerging national bullion market.
