If you’re a collector, donating from your collection instead of your bank account or investment portfolio can be tax-smart. When you donate appreciated property rather than selling it, you avoid the capital gains tax you would have incurred on a sale. And long-term gains on collectibles are subject to a higher maximum rate (28%) than long-term gains on most long-term property (15% or 20%, depending on your tax bracket) — so you can save even more taxes.
