I came across this thread the other day and it sparked my interest. Here is what I turned up.
To read Pub. L. No. 95-147, October 28, 1977, § 4(c), 91 Stat. 1227, 1229 (codified as amended at 31 U.S.C. § 5118(d)(2)), Click

According to TROSTEL v AMERICAN LIFE, (U.S. 8th Circuit Court of Appeals, No. 95-3666, 1998), 95-147 amended HJR -192 but only to the extent that gold clauses were allowed in contracts after 1977. In 1996, Congress reversed itself and disallowed gold clauses with this exception: "...unless all parties to the assignment or novation specifically agree to include a gold clause in the new agreement. " Congress then reversed itself one more time in 1997 when the legislation was signed into law by removing this sentence in its entirety. Go to the link and read the case, particularly the bolded text and the paragraphs which follow it.
Bottom line: after October 27, 1977, obligations issued containing gold clauses may be paid in gold.
I did not find anything indicating that HJR-192 had been repealed.
