Dolls, plates, and exhibits are coming to you at a low, low price

Thanks to Sunday papers, the Web, and TV commercials, hungry fans can feast on a virtual host of Diana trinkets. Here’s a sampling from this bizarre buffet:

THE SIERRA MINT, a former auto-parts manufacturer that once produced trim accessories for GM cars, offers its first commemorative coins: the $19.95 Diana coin, in ”royal German silver” or brass; the $49.95 piece in solid sterling silver. Each item is ”encapsulated in plastic and mounted on a display card.” The company will donate 5 percent of the gross, or $1 million (whichever is less), to the Diana, Princess of Wales Memorial Fund.

THE DIANA ORNAMENT ($25; glass display case for an extra $15) from NCM Studio Inc. in Buffalo. Net proceeds to children’s charities; artist Nancy Murnyack hopes to raise $1 million.

THE LIMITED-EDITION ”PEOPLE’S PRINCESS” PLATES for $24.95 from the Bradford Exchange, which will donate 18 percent of profits to ”her favorite” charities. Not to be confused with the $29.95 ”Princess Diana Tribute Plate” by the Franklin Mint, which will give all profits to charity.

THE DIANA DOLL ($195, also from the Franklin Mint), fully accessorized with tiara and handbag, garbed in a hand-beaded gown — much like the one the company bought for $151,000 at Christies last June. The company will donate $1.5 million to charity. Doll No. 2: clad in a copy of the velvet dress Di wore when she danced with John Travolta at the White House, from the Ashton-Drake Galleries — yours for just six payments of $22.99. Doll No. 3 — a ”royal purple” bear named ”Princess,” from the makers of Beanie Babies; all profits will go to Diana’s memorial fund.

AN EXHIBITION OF THE DRESSES OF THE PRINCESS OF WALES, an upcoming two-year world tour of 14 Di dresses bought at Christies, on loan from Maureen Rorech of Florida. The exhibit’s website has received 500,000 hits, and promoters hope to raise $100 million for charities.
