Almost all of Marjorie Jackson's earthly goods were auctioned off yesterday.

Her two Cadillacs, fur coats, jewelery, a tiny portable burglar alarm, clothing and household appliances - even the feathers of her dead pet parrot.

But not her gold inlaid false teeth.

Francis Feeney, attorney for the estate of the slain grocery-chain heiress, disclosed that he got a bill for $200,000 several days ago from a dentist for "dental work" for Jackson.

Feeney retrieved the partial plate from the Earls Auction Barn here as potential evidence in a possible law suit over the claim.

Widow jackson, a 66-year-old recluse, was found shot to death in her fire-damaged home here May 7. Police discovered about $5 million hidden around the house, and said they believed $3 million to $6 million more had been stolen. Six persons have been arrested in the case.

The auction drew buyers and the curious from as far away as California, Texas and New York. The crowd started driving in a cold steady rain at 6 a.m., and about 1,000 persons had jammed into a big tent when the sale started at 10:30 a.m.

There were brisk sales of such items as 30 pairs of children's pajamas (Jackson was childless), new clothing still bearing price tags, books (including 50 Bibles), music ("100 Best Songs of the '20s and '30s), china, silverware, furniture and two refrigerators. Every now and then auctioneer Earl Cornwell would hold up a plain dresser, drawer, in which police reportedly had found some of the millions.

Eunice Gibson, an elderly woman who bought one for $35 explained:

"It was one of those stupid impulses that hit us once in a lifetime. This is the one they found $2 million in - one of the auctioneers told me. I've been so terribly sorry for the dear lady . . . We should all fantasize once in awhile, and wonder what's around the bend . . ."

Jackson's plam-sized burglar alarm, which sells for perhaps $7.50 retail, was snapped up for $22.50.

Cornwell waved a voucher listing the retail price of Jackson's two 1976 Cadillac Sevilles at $13,677. The yellow one had 44 miles on it, and the metallic gold one 2,610.

Harold Smith, who described himself as retired, bought the yellow car for $14.000.

"I wanted one all my life," he explained. "Actually, I wanted a Mercedes Benz, but I'll settle for this."

Charlene Hodgin, who bought the gold car for $12,000, said she would keep it in her garage.

After dispatching 15 fine Oriental rugs and four full-length mink coats. Cornwell sold two shelves of jewelry plus the feathers of Boyd, jackson's prized pet parrot who died in 1967, reportedly at age 35.

One bunch of feathers drew $15, and two others $7.50 each. A pastel painting of Boyd sold for $22.50, and a paperweightwith his picture in it for $17.50.
