Hard to see, but of the current elements 'known to haaaarrvarrd" per the Tom Lehrer song, there are a few that would be rather diificult to scrape up. Beklinium, 97, has only ever been synthesized in picogram quantities, and Oganesson, 118 has a half life of less than a millisecond, it was actually only comfirmed because of it's breakdown into Livmorium 116
In October 2006 it was announced that three atoms of oganesson had been detected by the bombardment of californium-249 with calcium-48 ions, which then rapidly decayed into livermorium.[25]
The observation of the daughter 290Lv allowed the assignment of the parent to 294Og and confirmed the synthesis of oganesson.
But I've also seen somone actually make a Periodic "table" in the same fashion. IIRC the person who built it had to get special permission to include samples of Plutonium (and maybe Uranium, too) and put them in lead-lined compartments.

Sold on Amazon for ~$32.
The samples only go up to bismuth (83). The next, 84, polonium, is highly radioactive and is only represented by the triad symbol, as are most of the higher atomic numbers.
