Mammoth Fundraiser

February 16-17, 2019

The Annual Bonsai Garden at Lake Merritt Mammoth Auction & Sale will be held on Saturday, February 16 and Sunday, 17, 2018 at the Lakeside Garden Center in Oakland, CA.  This is an official appeal for materials for the Auction of quality bonsai on Saturday and the Sale of bonsai and pre-and-developing bonsai on Sunday.  Items may be donated or submitted on consignment.

Bonsai for the Auction will need to be submitted by December 30, 2018. Material for the Sunday Sale will be accepted at the Garden Center on Saturday, February 16th, 9am – 4pm and Sunday, February 17th, between 8am – 9am. Any bonsai material, pots, etc. will be accepted as sale material.  Consignment items for the Saturday Auction will have a 30% charge and for the Sunday Sale will have a 25% charge.  Again, full donations are appreciated and tax-deductible. Contact Mike Mello, 510-886-1568 or Dennis Hawkins, 510-657-8229 for more sale information. If you wish to place a reserve price on your item in the Auction, you will be charged a fee of 10% of that reserve if the item does not sell. This fee goes to help defray the cost of the auction.


Participation in the auction will require that upon arrival on Saturday, you REGISTER AND PURCHASE a catalog for $5 which includes a Bidder’s Card that you will need to make bids and record your purchases. The $5 covers the cost of printing and certifies everyone who is bidding. The catalog illustrates all of the items that will be auctioned, including a description of the physical characteristics of all material shown.

A successful bidder will receive an auction item number sticker on his/her Bidder’s Card by an auction official for each item purchased.  Each bidder is encouraged to record on their Bidder’s Card the purchase amount and item number.

Each item on the display tables has its own Auction Item Card displayed. The Auction Item Card will have the catalog number of the item, description, and indicate whether or not it has a reserve price (the reserve price amount will not be shown).

The auctioneer will determine the opening bid. Raises above the opening bid will be in approximately 10% increments. For instance, an item with a minimum bid of $250 will be raised in increments of $25.  If the reserve price for the item is not reached the item will be removed from the auction.

An auction official will record the Bidder number and purchase price on the Auction Item Card and will be brought by an auction official directly to the cashier.  After check out and payment the Auction Item Card(s) will be retained for GSBF Bonsai Garden at Lake Merritt records.

A Bidder may exit the auction at any time when his/her bidding is complete.  Bring your Bidder’s Card to the cashier handling your Bidder number.  You may pay by credit card, check or cash. The cashier will have the Auction Item Card(s) for each item you have purchased.  This can be cross-checked with your record of purchased items on your Bidder’s Card. If any dispute arises during the auction, it shall be reviewed by the auction chairs and their resolution will be final.

Item(s) may be removed from the display tables when the purchaser is ready to leave the auction room and has his/her Bidder’s Card marked PAID with an official cashier’s signature.  For purposes of security, this signed Bidder’s Card will be checked at the exit door.
